In this portal, Sanatan Dharma is presented as a broad, internally diverse family of Indian religious, philosophical, ethical and cultural traditions rather than a single creed with one founder or one mandatory theology. Its vocabulary includes dharma, karma, ātman, Brahman, mokṣa, bhakti, yoga, pūjā, pilgrimage and many schools of thought.

Read in the portal / sources: Chapter 4 · Chapter 45

The terms overlap, but they are not identical in every context. “Hinduism” is a modern umbrella term used in scholarship and public life, while “Sanatan Dharma” is a traditional expression meaning roughly an enduring or eternal dharma. The portal uses both carefully and explains the historical problem of treating a huge family of traditions as a single uniform religion.

It can be both, depending on what aspect is being discussed. It includes worship, sacred texts, temples, festivals and pilgrimage, but also philosophy, ethics, family practice, social institutions, art and everyday duties. Calling it only a “way of life” can therefore be too narrow, just as reducing it to a single creed can be too narrow.

Read in the portal / sources: Chapter 48 · Chapter 55

No. The traditions represented in the portal emerged over very long periods and through many communities, texts, teachers and philosophical schools. Vedic revelation, Upanishadic dialogues, epics, Purāṇas, sectarian traditions, regional practices and later teachers all contributed to the historical landscape.

Read in the portal / sources: Chapter 2 · Chapter 3 · Chapter 43

No. The Vedas, Upaniṣads, Rāmāyaṇa, Mahābhārata and Bhagavad Gītā, Purāṇas, Dharmaśāstra works, Āgamas/Tantras and many regional languages and traditions all matter in different communities. Authority is therefore layered rather than concentrated in one book.

Read in the portal / sources: Chapter 3 · Chapter 11 · Chapter 44

There is no single checklist that fits every tradition. Beliefs about God, gods, ultimate reality, self, ritual and liberation differ among Vedānta, Sāṃkhya, Yoga, Śaiva, Śākta, Vaiṣṇava, Smārta and other traditions. Even karma is not a sufficient test for identifying every Hindu philosophy.

“Pagan” is a broad label from other religious histories, not a native name for these Indian traditions. The portal shows why the label can mislead: some traditions are devotional and theistic, some are non-dual or strongly philosophical, and Hindu schools have debated reality, self and God for centuries. “Polytheistic” also does not describe the whole field adequately.

Some traditions worship many deities, but the underlying theology varies. A practitioner may understand deities as distinct divine persons, manifestations of one ultimate reality, or objects of a particular devotional path. Some philosophical schools place ultimate reality beyond any simple one-god/many-gods classification.

Read in the portal / sources: Chapter 5 · Chapter 13 · Chapter 16

Yes. The philosophical traditions include paths centered on knowledge, meditation, disciplined action, devotion, ritual, or combinations of these. The portal also discusses traditions in which ultimate reality is treated in highly abstract or non-dual terms.

Read in the portal / sources: Chapter 9 · Chapter 103 · Chapter 104

Plurality is one of its strongest historical features, but “tolerance” should not be romanticized as perfect harmony. The history includes debate, rivalry, sectarian competition and synthesis. The portal therefore presents pluralism together with disagreement.

Read in the portal / sources: Chapter 18 · Chapter 32 · Chapter 66

Different communities developed different devotional relationships with deities such as Viṣṇu, Śiva, Devī, Gaṇeśa, Sūrya and many local gods and goddesses. In some theologies these are distinct forms of divinity; in others they are understood as expressions of one ultimate reality.

Read in the portal / sources: Chapter 12 · Chapter 16

That is one possible theological interpretation, but it is not the only one. Advaita can interpret divine plurality through non-dual Brahman, while Vaiṣṇava, Śaiva and Śākta traditions make different claims about the supreme status of Viṣṇu, Śiva or Devī.

Read in the portal / sources: Chapter 10 · Chapter 14 · Chapter 15

Brahman is the name used in the Upaniṣadic and Vedāntic traditions for ultimate reality. Its interpretation varies: Advaita identifies it with non-dual reality, while qualified and dualist Vedānta gives different accounts of the relation between Brahman, souls and the world.

Ātman generally means the self, but its philosophical interpretation varies. In major Upaniṣadic and Vedāntic discussions it is connected to the deepest question of what a person really is; Advaita famously identifies Ātman and Brahman, while other Vedānta schools distinguish the individual self from God in different ways.

Both descriptions occur, depending on the tradition. In Vaiṣṇava traditions Krishna may be understood as an avatar of Viṣṇu or, in Gauḍīya theology, as the supreme source from whom Viṣṇu forms proceed. The portal treats these as theological differences rather than forcing one answer.

Read in the portal / sources: Chapter 14 · Chapter 19 · Chapter 87

Śaiva traditions commonly regard Śiva as supreme, but the philosophical meaning of that supremacy differs among schools. The portal covers Pāśupata, Śaiva Siddhānta, Kashmir Śaivism and other traditions rather than presenting one universal Śaiva theology.

Read in the portal / sources: Chapter 15 · Chapter 86

Śākta traditions understand Devī or Śakti as divine power and, in some schools, as the ultimate reality itself. The divine feminine also appears in Vaiṣṇava, Śaiva, Purāṇic and regional traditions. The portal therefore treats Goddess worship as a major theological and cultural stream, not a side topic.

Read in the portal / sources: Chapter 13 · Chapter 16 · Chapter 88

Gaṇeśa is widely associated with auspicious beginnings, removal of obstacles and learning. The precise theology and ritual sequence varies by community. The portal places such devotional practices within the wider development of Purāṇic and sectarian theism.

Read in the portal / sources: Chapter 12 · Chapter 48

An avatar is a descent or manifestation of a deity, especially associated with Viṣṇu in Vaiṣṇava traditions. The best-known examples include Rāma and Krishna. Different traditions interpret avatarhood differently, and the concept should not be treated as a single fixed doctrine.

Read in the portal / sources: Chapter 14 · Chapter 81

Sanatan traditions have historically incorporated regional, village and lineage-based worship. Kuldevtas, Kuldevis and Gramadevatas connect religious practice to family memory, locality, protection, fertility, healing and community identity.

Read in the portal / sources: Chapter 21 · Chapter 117 · Chapter 118

Cremation is an ancient Indian funerary practice associated with the transformation and release of the body. In many Hindu traditions the body is treated as temporary, while funeral rites help mark separation from the deceased body and guide the dead through the next stage of existence. But cremation is not universal: burial and other practices also occur.

No. Cremation is widespread but not universal. Historical and regional variation includes burial, and some communities follow distinctive funerary practices. The portal emphasizes that “Hindu practice” cannot be reduced to one ritual rule.

There is no single answer. Traditions describe rebirth, ancestral realms, heavenly or difficult realms, preta states and liberation in different ways. The common philosophical framework is that death is not necessarily the end of the individual story.

Saṃsāra is the cycle of repeated birth, death and rebirth. In many Hindu philosophies it is sustained by karma and ignorance or attachment, and liberation means release from this cycle. The Upaniṣadic development of these ideas is historically layered rather than instantaneous.

Mokṣa means liberation. It is generally described as release from saṃsāra, but schools disagree about what liberation is: non-dual realization, eternal relation with God, freedom of consciousness, or other forms of final release.

Read in the portal / sources: Chapter 9 · Chapter 10 · Chapter 103

There is no single universal recipe. Major paths include disciplined action without attachment to its fruits, knowledge of reality and self, meditation, devotion and surrender, depending on the school. The Bhagavad Gītā presents several paths in combination, while Vedānta and Yoga interpret liberation differently.

Not necessarily. In many philosophical systems good karma produces beneficial results but remains within the causal order of saṃsāra. Liberation requires a deeper transformation—such as knowledge, devotion, detachment or realization—depending on the tradition.

The phrase “84 lakh yonis” means 8.4 million forms or modes of birth in popular Hindu religious discourse. The portal distinguishes this traditional number from modern biological species counts: it is a religious cosmological motif, not a census produced by modern biology.

Read in the portal / sources: Chapter 114 · Chapter 125

Yama is a major Vedic and later Hindu figure associated with death and the realm of the dead. The Ṛgveda already presents Yama as the first mortal and ruler of the dead, while later traditions elaborate his role in judgment and afterlife imagery.

Ancestor rites connect the living and the dead through remembrance, offerings and family duty. The importance of ancestors is visible in Vedic, Dharmaśāstra, Purāṇic and regional practice, although details vary.

Read in the portal / sources: Chapter 116 · Chapter 80

No—not in the simplest sense. Karma means action and its consequences; many Hindu philosophical accounts explicitly leave room for present action to affect future outcomes. Treating karma as “everything is predetermined” is therefore too crude.

Some traditions interpret suffering through karma across lifetimes, but the portal warns against turning that idea into a simplistic moral verdict on every victim. Karma is a complex philosophical doctrine, and different schools disagree about causation, agency and how karma is known.

Yes. The Upaniṣadic and later traditions do not treat karma only as a record of the past; present action can generate consequences. The Bhagavad Gītā also emphasizes disciplined action and freedom from attachment to results.

Dharma can mean moral order, duty, law, right conduct, teaching or the pattern that sustains a social and cosmic order. Its meaning changes with context, which is why the portal avoids translating it with one English word everywhere.

Read in the portal / sources: Chapter 4 · Chapter 80

Not exactly. Dharma can describe religious duty, ethical obligation, social responsibility, law and the sustaining order of life. It is broader and more context-sensitive than the modern English word “religion.”

Read in the portal / sources: Chapter 4 · Chapter 58

They are dharma, artha, kāma and mokṣa: ethical order, material well-being, legitimate desire/pleasure and liberation. Different texts and schools balance them differently, and the scheme should not be treated as a rigid four-step program.

Read in the portal / sources: Chapter 9 · Chapter 56

No. Kāma is one of the recognized aims of human life. The tradition instead asks how desire is disciplined, integrated with dharma and related to attachment. Ascetic and renunciant paths may place much stronger emphasis on overcoming desire.

Read in the portal / sources: Chapter 9 · Chapter 29 · Chapter 69

Ahiṃsā became a major ethical ideal across Indian traditions, including Hindu, Buddhist and Jain contexts. But historical practice is more complicated: texts also discuss sacrifice, warfare, punishment and duties that can involve force. The portal presents both the ideal and the historical complexity.

Read in the portal / sources: Chapter 17 · Chapter 110

Ideas about merit, demerit, ritual efficacy and transfer of religious benefit occur in Indian traditions, but they should not be confused with a simple “karma points” system. The portal treats karmic causation as philosophically diverse and historically developing.

Read in the portal / sources: Chapter 115 · Chapter 121

Both kinds of language exist. Non-dual traditions emphasize realization of ultimate reality, while devotional traditions may emphasize divine grace, surrender and loving relationship with God. The Gītā itself combines disciplined action, knowledge and devotion.

The cow became a powerful religious symbol through several overlapping meanings: nourishment through milk, association with generosity and prosperity, ritual value, pastoral life and later ethical ideas about non-harm. The portal stresses that the history is long and not reducible to one single origin story.

There is no single answer for every historical or contemporary community. Many Hindu traditions strongly prohibit or avoid beef and cow slaughter, while historical evidence shows that food practices were not uniform across all periods and texts. Today practice varies by community, region, family and individual.

The historical record is complicated. Early Vedic and later Dharmaśāstra materials contain different discussions of cattle, sacrifice and meat, and scholars disagree about how to interpret particular passages. The portal therefore rejects both extremes: “Indians always ate beef” and “no Indian ever ate it.”

No universal rule applies to every Hindu community. Vegetarianism is highly valued in many traditions, especially where ahiṃsā, ritual purity and devotional practice are emphasized, but historical and regional dietary practices have been diverse.

Prasāda is food or another offering understood as sanctified after being presented to a deity. Sharing it turns eating into a religious act of receiving and distributing blessing. Practices vary widely by temple and tradition.

Read in the portal / sources: Chapter 48 · Chapter 99

Fasting can express discipline, devotion, purification, remembrance, vows and festival observance. It is not one uniform practice: some fast completely, others avoid particular foods, and rules differ by festival, region, sect and health circumstances.

Read in the portal / sources: Chapter 70 · Chapter 99

Different texts and traditions answer differently. Some strongly condemn killing or eating animals; others permit meat under defined conditions. The portal highlights this diversity and the long historical movement toward stronger vegetarian and ahiṃsā ideals.

Animals can symbolize divine qualities, participate in myth, serve as deity vehicles (vāhanas), or become part of ritual and local sacred geography. The cow, snake, elephant, monkey and Garuḍa are especially prominent, but the symbolic system is much wider.

Read in the portal / sources: Chapter 100 · Chapter 125

No. Reverence for cattle has deep textual, ritual and social histories. At the same time, modern cow-protection politics has its own nineteenth- and twentieth-century history. The portal keeps those layers separate instead of treating a modern political movement as the origin of the religious symbol.

Some traditions historically and presently include forms of animal sacrifice, while others reject them and emphasize vegetarian offerings. The portal treats sacrifice as a diverse ritual history rather than assuming one practice for all Hindus.

The Vedas are the foundational śruti corpus, traditionally comprising Ṛg, Sāma, Yajur and Atharva Veda. Each has layered materials, including Saṃhitā, Brāhmaṇa, Āraṇyaka and Upaniṣadic texts.

Read in the portal / sources: Chapter 2 · Chapter 3

Śruti means “that which is heard” and refers especially to revealed Vedic literature. In the traditional hierarchy it is distinguished from smṛti, “that which is remembered,” which includes later bodies of religious and legal literature.

Read in the portal / sources: Chapter 3 · Chapter 44

Smṛti is a broad category of remembered or transmitted authoritative literature, including Dharmaśāstra, epics and Purāṇas. Its authority and interpretation vary by tradition and historical setting.

Read in the portal / sources: Chapter 44 · Chapter 80

No. The Bhagavad Gītā is a section of the Mahābhārata, specifically the Bhīṣma Parvan. It became one of the most influential texts for later Hindu philosophy, devotion and ethics.

Read in the portal / sources: Chapter 11 · Chapter 76

They combine genealogy, cosmology, theology, pilgrimage, ritual, sacred geography and stories. They should not be forced into a modern binary of “history versus fiction”; the portal uses different methods to analyze their literary, ritual and cultural functions.

Read in the portal / sources: Chapter 12 · Chapter 79 · Chapter 50

The Rāmāyaṇa developed through many recensions, regional languages, performance traditions and retellings. Vālmīki’s Sanskrit epic is foundational, but Tamil, Awadhi, Bengali, Assamese, Odia, Kannada, Telugu and Southeast Asian versions developed their own emphases.

Read in the portal / sources: Chapter 76 · Chapter 77

No. The critical edition is a scholarly reconstruction from manuscripts, while regional and devotional traditions preserve many expansions and interpretive worlds. “Many Mahābhāratas” is therefore a useful way to describe the textual and cultural history.

Read in the portal / sources: Chapter 78 · Chapter 81

No. Sanskrit is central to many pan-Indian textual traditions, but regional languages became major vehicles of philosophy and devotion. Tamil bhakti, Bengali Vaiṣṇavism, Marathi Vārkarī literature, Awadhi Rām-bhakti and many other vernacular traditions are essential to the history.

Read in the portal / sources: Chapter 20 · Chapter 90

Yes. Indian traditions developed extensive commentarial cultures, debate and competing schools of interpretation. Vedānta alone contains major disagreements over Brahman, self, world, knowledge and liberation.

Read in the portal / sources: Chapter 10 · Chapter 104

A murti is a sacred image or embodied form used in worship. In many traditions the image is ritually installed and becomes a focus for darśan—seeing and being seen by the deity. The portal treats murti worship as a sophisticated ritual theology, not simply “idol worship.”

Read in the portal / sources: Chapter 48 · Chapter 68

That is too simple. Ritual traditions can understand a consecrated image as a locus or embodied presence of the deity, while philosophical interpretations vary. The point is relational and ritual as much as material.

Read in the portal / sources: Chapter 94 · Chapter 68

Darśan means seeing, viewing or beholding, and in temple practice it can describe the encounter between worshipper and deity. The concept is important because worship is not only about asking for something; it is also about presence, relationship and recognition.

Read in the portal / sources: Chapter 126 · Chapter 68

Pūjā is a broad family of worship practices involving offerings, gestures, recitation, attention and relationship with a deity. Household and temple forms differ considerably.

Read in the portal / sources: Chapter 99 · Chapter 48

Ārati is a ritual offering of light, often using a lamp moved before a deity. It is both visual and participatory: light, music, gesture and communal attention can combine in the ceremony.

Read in the portal / sources: Chapter 99 · Chapter 68

Temple bells can mark entry into sacred space, focus attention and accompany ritual worship. Meanings vary by temple and tradition, so the portal avoids claiming one universal theological explanation.

Read in the portal / sources: Chapter 68 · Chapter 99

Flowers are common offerings because they are beautiful, perishable and associated with freshness and devotion. Particular flowers also have associations with particular deities and rituals.

Read in the portal / sources: Chapter 99 · Chapter 101

Fire is central to Vedic ritual, while lamps become a major feature of later temple and household worship. Fire and light can symbolize transformation, presence, offering and knowledge.

Read in the portal / sources: Chapter 2 · Chapter 99

A temple is more than a prayer hall. It can be a sacred cosmos, ritual center, economic institution, artistic environment, pilgrimage destination and community hub.

Read in the portal / sources: Chapter 48 · Chapter 68

Pilgrimage turns sacred geography into a lived religious practice. A tīrtha can be a river, shrine, mountain or other crossing-place where physical travel is connected with purification, devotion, memory and transformation.

Read in the portal / sources: Chapter 124 · Chapter 126

Vedānta is a family of philosophical traditions built around the Upaniṣads, Bhagavad Gītā and Brahma Sūtras. Advaita, Viśiṣṭādvaita and Dvaita are major schools, but the field is broader than those three.

Read in the portal / sources: Chapter 10 · Chapter 104

Advaita means “non-dual.” In Śaṅkara’s influential interpretation, ultimate reality is Brahman and liberation involves knowledge that overturns mistaken identification with limited individuality. Later Advaita traditions developed the system further.

Read in the portal / sources: Chapter 10 · Chapter 89

Dvaita, associated especially with Madhva, emphasizes a real distinction between God, individual souls and the world. It is a major Vaiṣṇava philosophical school and differs sharply from Advaita on the status of difference.

Read in the portal / sources: Chapter 10 · Chapter 87

Viśiṣṭādvaita, associated with Rāmānuja, describes a qualified non-dualism in which Brahman is one but includes real distinctions within a unity. It became foundational for Śrī Vaiṣṇava theology.

Read in the portal / sources: Chapter 10 · Chapter 87

Sāṃkhya is a philosophical system that analyzes reality through principles including puruṣa (consciousness) and prakṛti (nature). It became deeply connected with Yoga and influenced later Indian thought.

Read in the portal / sources: Chapter 103 · Chapter 45

Yoga is not only physical postures. Classical Yoga concerns the discipline of mind and consciousness, with ethical practices, concentration, meditation and liberation. Modern postural yoga is one later part of a much larger history.

Read in the portal / sources: Chapter 103 · Chapter 47

Yoga has religious, philosophical, meditative and physical dimensions. Classical Yoga is embedded in an Indian soteriological framework, while modern global yoga can be practiced as exercise, wellness, meditation or spirituality. The portal distinguishes these historical layers.

Read in the portal / sources: Chapter 47 · Chapter 103

Bhakti means devotion or loving participation in relation to a deity or divine reality. Bhakti traditions range from highly personal devotion to sophisticated philosophical accounts of divine love and surrender.

Read in the portal / sources: Chapter 20 · Chapter 109

Yes, in many Vaiṣṇava, Śaiva and Śākta traditions. Devotion can be treated as a direct path, a form of knowledge, or a means of receiving divine grace. The Gītā is a major source for later discussions of bhakti.

Tantra refers to diverse ritual and philosophical traditions, especially associated with Śaiva and Śākta worlds. It can involve mantra, visualization, deity practice, initiation, subtle-body practices and distinctive ritual systems. It should not be reduced to sexuality.

Read in the portal / sources: Chapter 39 · Chapter 88

Caste in India involves the complex interaction of varṇa ideology, thousands of jātis, occupation, marriage, region, political power and historical institutions. Some religious texts helped articulate social hierarchy, but the actual caste system cannot be reduced to a single scripture or simple theological rule.

Read in the portal / sources: Chapter 46 · Chapter 80

No. Varṇa is a four-part classificatory scheme found in Sanskrit literature; jāti refers to concrete social communities, of which there are many. Historians and anthropologists caution against treating the two as exact synonyms.

Read in the portal / sources: Chapter 46 · Chapter 80

Yes. The portal highlights figures such as Gargī, Maitreyī, Lopāmudrā, Āṇḍāl and Akka Mahādevī. Their historical contexts differ, and their presence should not be used to erase real gender restrictions in other periods.

Read in the portal / sources: Chapter 7 · Chapter 8 · Chapter 113

Gargī Vācaknavī is a famous Upaniṣadic interlocutor who debates Yājñavalkya in the Bṛhadāraṇyaka Upaniṣad. Her questions concern the deepest structure of reality and became a major example of women’s participation in classical Indian intellectual traditions.

Read in the portal / sources: Chapter 7 · Chapter 113

Maitreyī appears in the Bṛhadāraṇyaka Upaniṣad in a dialogue about wealth, immortality and the self. Her questions redirect the conversation from material possession to the deeper problem of what makes immortality meaningful.

Read in the portal / sources: Chapter 8 · Chapter 113

Yes. Women have participated in devotional, monastic, yogic and ascetic traditions, although institutional access has varied by time and community. The portal includes women saints and modern institutions as part of this history.

Read in the portal / sources: Chapter 37 · Chapter 113

There is historical evidence for women teachers, saints and gurus, but authority structures have varied. The portal emphasizes lineage, institution and community recognition rather than presenting a single rule.

Read in the portal / sources: Chapter 40 · Chapter 113

That blanket label is too broad to describe a tradition with both patriarchal institutions and powerful traditions of female divinity, women philosophers, poets, saints and ascetics. A serious account has to hold those tensions together rather than selecting only one side.

Read in the portal / sources: Chapter 13 · Chapter 46 · Chapter 113

Historically its traditions are rooted in South Asia, but they have never been limited to one modern nation-state. Today Hindu traditions are practiced across the global diaspora, with temples and communities adapting to new contexts.

Read in the portal / sources: Chapter 64 · Chapter 67

Yes. Contemporary Hindu traditions are practiced globally, and many communities have developed outside South Asia. The portal treats diaspora as part of the living modern history rather than a contradiction of Indian origins.

Read in the portal / sources: Chapter 64 · Chapter 66

The portal distinguishes archaeological continuity from direct textual identity. The Indus civilization predates the earliest securely dated Vedic texts, and scholars debate which cultural features can be connected across the transition. It is safer to discuss continuities and uncertainties than to claim a simple one-line origin story.

Read in the portal / sources: Chapter 1 · Chapter 43

The portal does not claim that. Epics contain layered literary, theological and cultural traditions. Archaeology can illuminate places and historical contexts, but it cannot automatically verify every narrative detail.

Read in the portal / sources: Chapter 43 · Chapter 50 · Chapter 76

The Ganga is both a physical river system and a sacred river with major theological, ritual, pilgrimage and civilizational significance. Its sacred geography includes bathing, pilgrimage, festivals, temples and river-centered memory.

Read in the portal / sources: Chapter 122 · Chapter 124

Mountains can be understood as abodes of deities, places of ascetic practice, pilgrimage destinations and symbols of vertical movement toward the sacred. The portal explores the Himalaya, Kailāsa, Govardhan and Arunachala as different forms of sacred place.

Read in the portal / sources: Chapter 123 · Chapter 126

Tīrtha literally evokes a crossing or ford and came to describe sacred places through which people seek spiritual transition. Rivers, temples, mountains and pilgrimage centers can all become tīrthas.

Trees can be sacred because they provide food, shade, medicine and habitat, while also becoming symbols of life, fertility, continuity and divine presence. Tulasī, bilva, aśvattha, banyan and lotus traditions illustrate different forms of sacred ecology.

Read in the portal / sources: Chapter 101 · Chapter 125 · NCERT — Sacred ecology

It contains strong traditions of reverence for rivers, forests, animals, mountains, trees and the elements, but religious symbolism does not automatically produce modern environmental protection. The portal distinguishes sacred ecology as an ethical resource from measurable environmental outcomes.

Jyotiṣa is a traditional Indian knowledge system concerned with calendrical calculation, astronomy and astrology. Its historical components should not be collapsed into modern astronomy: observational astronomy and astrological interpretation have different epistemic aims.

Read in the portal / sources: Chapter 120 · Chapter 53

No. They historically interacted in India, especially through calendars and planetary calculations, but modern astronomy is an empirical natural science while astrology makes interpretive claims about human life that are not established by modern scientific evidence.

Read in the portal / sources: Chapter 120 · Chapter 53

There is no single “Hindu science” doctrine. Indian traditions developed mathematics, astronomy, medicine, logic and theories of knowledge, while modern science operates through contemporary empirical methods. The portal asks what can actually be documented as historical inheritance rather than claiming that every modern discovery was anciently known.

Read in the portal / sources: Chapter 53 · Chapter 54 · Chapter 61

Why these answers are cautious

Tradition ≠ one uniform rule

Sanatan traditions contain competing schools, regional customs and historical changes. “Hinduism says…” is often too blunt; this page names the relevant tradition when the distinction matters.

Text ≠ modern science

Claims about karma, rebirth, lokas or sacred numbers are presented as religious or philosophical teachings, not as laboratory findings. Conversely, historical claims are not treated as proven simply because they appear in a sacred text.

Portal first, then wider scholarship

Every answer links to the relevant chapter(s) of this portal. External links point to recognizable scholarly, university, institutional or primary-text resources that readers can inspect themselves.
