Question 1: What is the fundamental difference between Shruti and Smriti?
Answer:
The distinction between these two categories defines the hierarchy of authority in Hindu thought:
Smriti (“That which is remembered”): These are human-authored texts that interpret and apply the eternal truths of Shruti to specific historical or social contexts. This includes the Itihasa (Ramayana, Mahabharata), Puranas, and Dharma Shastras. While highly respected, their authority is secondary to Shruti.
Shruti (“That which is heard”): These are considered Apaurusheya (not of human origin). They are eternal truths “heard” by ancient Rishis (seers) in deep meditative states. The Vedas and Upanishads fall under this category. They are the supreme authority; if a later text contradicts Shruti, the Shruti prevails.
Question 2: How are the schools of Indian philosophy divided into Astika and Nastika?
Answer:
Contrary to common western definitions of “theism,” this division is based on the acceptance of Vedic authority, not necessarily the belief in a creator God.
Nastika (Heterodox): These schools reject the authority of the Vedas. The three primary schools are Buddhism, Jainism, and Charvaka (a materialist school).
Astika (Orthodox): These schools accept the Vedas as the ultimate source of knowledge. There are six major schools (Shad-Darshanas): Nyaya, Vaisheshika, Samkhya, Yoga, Mimamsa, and Vedanta.
Question 3: What is the central role of the Upanishads in Hindu philosophy?
Answer:
The Upanishads represent the Jnana-Kanda (Knowledge Section) of the Vedas, shifting the focus from external rituals to internal realization.
The Nexus: They introduce the foundational relationship between Brahman (the infinite, universal reality) and Atman (the individual soul), proposing that at the highest level, they are one and the same.
The Philosophical Core: They form the basis of Vedanta (the “end” or “climax” of the Vedas).
Core Inquiry: They move away from “How do I perform this ritual?” to “Who am I?” and “What is the nature of reality?”
