Itihāsa & Purāṇa
The Smriti layer — narratives that carry dharmic teaching through story, lineage, and cosmology.
18 Parvas · 100,000 Verses
The longest epic in world literature. The Kurukshetra war between the Pāṇḍavas and Kauravas is the frame for the most comprehensive account of dharma, statecraft, and cosmic order in any tradition. The Bhagavad Gita is embedded in its 6th parva.
Contains the Bhagavad Gita — Bhīṣma Parva, chapters 25–42
7 Kāṇḍas · 24,000 Ślokas
The first poem — Ādikāvya — composed by the sage Vālmīki. The journey of Rāma from Ayodhyā through exile in the forest, the abduction of Sītā by Rāvaṇa, and the great battle of Laṅkā. The ideal of dharmic kingship and devoted love.
Vālmīki — "the first poet" — composed this in anuṣṭubh metre after witnessing a heron shot by a hunter
18 Mahāpurāṇas · 400,000+ Verses
The encyclopaedia of the tradition — cosmology, genealogy, devotion, ritual, philosophy, and the great cycles of creation and dissolution. The Bhāgavata Purāṇa, Viṣṇu Purāṇa, and Śiva Purāṇa each tell the same cosmos from a different center.
"Purāṇam" — that which renews what is ancient. The Purāṇas make the Vedic world accessible.
Darśana
The āstika darśanas — six systematic inquiries into reality, knowledge, and liberation. Grouped as three traditional mithuna pairs.
Liberation through tattvajñāna — correct knowledge of the 12 prameyas. Valid reasoning is the primary instrument.
Reality consists of 6 padārthas — dravya, guṇa, karma, sāmānya, viśeṣa, samavāya — built from eternal paramāṇus.
25 tattvas unfold from Prakṛti. Liberation is viveka — the Puruṣa recognising its absolute separation from Prakṛti.
Yogaś citta-vṛtti-nirodhaḥ. Liberation through the aṣṭāṅga path. Accepts Sāṃkhya's metaphysics but adds Īśvara.
Dharma is what the Veda enjoins — codanālakṣaṇo'rtho dharmaḥ. The Veda is apauruṣeya: eternal, unauthored.
Inquiry into Brahman, Ātman, and their relation via the Prasthānatraya: Upanishads, Brahma Sūtras, Bhagavad Gita.
Comparative Philosophy
Pramāṇa · Tattva · Ātman · Mokṣa — how each school answers differently
| School | Pramāṇa | Tattva | Ātman | Mokṣa |
|---|---|---|---|---|
| Nyāya | 4 — pratyakṣa, anumāna, upamāna, śabda | 16 topics of inquiry (ṣoḍaśa padārtha) | Individual, eternal, bound by karma | Tattvajñāna — knowledge liberates from duḥkha |
| Sāṃkhya | 3 — pratyakṣa, anumāna, āgama | 25 tattvas — 1 Puruṣa + 24 Prakṛti evolutes | Plural, eternal, passive witness. Nirīśvara | Viveka — discriminating Puruṣa from Prakṛti |
| Vedānta | 3 — pratyakṣa, anumāna, śruti (Prasthānatraya) | Varies: Advaita (Brahman only) · Viśiṣṭādvaita (qualified non-dual) · Dvaita (5 eternal distinctions) | Varies — not a single answer across sub-schools | Varies: jñāna (Advaita) · bhakti (Rāmānuja) · prapatti (Madhva) |
| Vaiśeṣika · Yoga · Mīmāṃsā shown in full matrix — open to compare all six | ||||
Note: Vedānta row reflects the range across Advaita, Viśiṣṭādvaita, and Dvaita — not a single school.
Source-grounded exploration
What does the Bhagavad Gita say about action without attachment?
The Gita's central teaching appears in 2.47 — one is entitled to perform action, but not to claim its fruits. This is the foundation of karma yoga. Shankaracharya's Advaita reading treats this as preparation for jnana: desireless action purifies the mind until knowledge of the Self arises. Ramanujacharya's Vishishtadvaita view holds that action offered to God is itself a direct path to liberation.
