The six systems of Indian philosophy discussed in Pavan K. Varma’s Echoes of Eternity: A Journey Through Indian Thought from the Rigveda to the Present are Nyaya, Vaisheshika, Samkhya, Yoga, Purva Mimamsa and Vedanta. Varma’s Scroll excerpt, published April 4, 2025, introduces them as distinct approaches to knowledge, reality, disciplined practice, Vedic ritual and liberation—not as the only philosophical traditions in India.
What the book excerpt covers
Varma’s book traces Indian thought across a long historical span, from the Rigveda to the present. The Scroll selection focuses on six systems conventionally grouped as orthodox Hindu darshanas. That traditional grouping distinguishes them from heterodox traditions such as Buddhism and Jainism; it does not mean that Indian philosophy consists only of these six schools. OpenStax’s introduction to classical Indian philosophy offers an overview of the taxonomy.
The schools are often introduced in three pairs—Nyaya with Vaisheshika, Samkhya with Yoga, and Mimamsa with Vedanta. The pairings help orient readers, but each system has its own questions and arguments. Varma’s excerpt gives its clearest descriptions of the first five; it names Vedanta as the sixth and discusses Shankara’s later systematic exposition without supplying a full account of Vedanta itself.
What are the six systems?
Nyaya: reasoning and valid knowledge
Nyaya foregrounds logic, debate and the means by which knowledge can be justified. In Varma’s account, its principal means of knowledge are perception, inference, analogy and testimony. Its place in the Nyaya-Vaisheshika pairing reflects a broad association between inquiry into valid reasoning and inquiry into what exists.
#1 Best Overall
Vaisheshika: categories of reality
Varma presents Vaisheshika through atomism, pluralism and categories that include both material and nonmaterial reality. This is a philosophical account of the world, not a version of modern scientific atomic theory. The school’s association with Nyaya makes the pair a useful way to consider how reasoning relates to an account of reality.
Samkhya: distinguishing consciousness from nature
Samkhya describes reality in terms of prakriti, material nature, and purusha, consciousness. In the excerpt’s account, liberation depends on discerning that these are distinct. This framework makes the relation between consciousness and matter central to the school’s analysis.
Rank #2
Yoga: disciplined practice and meditation
Yoga broadly shares Samkhya’s framework but emphasizes the practices through which a person may realize the separation of consciousness from material nature. Varma writes: “The Yoga school broadly accepts the worldview of the Sankhya, but fleshes out the physical discipline and meditational regimen required by an individual to realise the separation (kaivalya) of Purusha, pure consciousness, from the non-sentient Prakriti.” The excerpt outlines an eight-part discipline and says Yoga differs from Samkhya in accepting a personal god.
Purva Mimamsa: Vedic ritual and dharma
Purva Mimamsa centers on Vedic ritual, dharma and the interpretation of prescribed action. Varma contrasts this orientation with a path to liberation through knowledge. Its pairing with Vedanta is a way to compare approaches to Vedic texts and religious life, not evidence that the two schools teach the same thing.
Vedanta: a broad tradition, not one single position
The excerpt identifies Vedanta as the sixth system and presents Shankara’s exposition as a later systematic account. It does not develop a full explanation of Vedanta, so the passage alone should not be treated as a survey of the school. Vedanta also contains distinct traditions: publisher descriptions identify Advaita, Vishishtadvaita and Madhva Vedanta among its forms. Oxford University Press’s reference listing includes chapters on Vedanta alongside the other five systems.
How to compare the schools
Rather than treating the six names as a checklist of interchangeable doctrines, compare them by the problems they address:
Rank #4
- Knowledge: What counts as a sound means of knowing? Nyaya’s focus on perception, inference, analogy and testimony makes this question explicit.
- Reality: What kinds of things exist? Vaisheshika is presented through categories of material and nonmaterial reality, while Samkhya distinguishes nature from consciousness.
- Consciousness and matter: How are they related, and can they be distinguished? This is central to Samkhya and to Yoga’s account of liberation through practice.
- Practice and liberation: Is the route emphasized disciplined physical and meditative practice, as in Varma’s presentation of Yoga, or knowledge, as in his contrast with Purva Mimamsa?
- Texts, ritual and the divine: What role do Vedic interpretation and prescribed ritual play, and does a school accept a personal god? The excerpt raises these distinctions most directly in its accounts of Mimamsa and Yoga.
These questions clarify the value of the three traditional pairings without collapsing their differences. Motilal Banarsidass’s overview of Hindu philosophy also describes the schools through these paired divisions and their differing emphases.

The passage is a book excerpt, not a standalone scholarly survey. Its historical dating and attributions are Varma’s account. For example, he dates the Nyaya Sutra to the third century BCE and attributes it to Gautama; he dates Patanjali’s Yoga Sutra to before 400 CE while noting disagreement about the earlier tradition. Those details should be read as claims made in the excerpt, not as an independent resolution of scholarly debates.
