Short for the Bhāgavata Purāṇa (or Srimad Bhagavatam) — one of the major Hindu scriptures, centered on the life and teachings of Krishna and composed roughly between the 8th and 10th centuries CE. Distinct from the Bhagavad Gita (which is a chapter of the Mahabharata), though both are foundational texts on dharma, devotion, and the nature of action. Referenced in Karthik's notes as a source of operating wisdom rather than religion — particularly on duty, detachment from outcomes, and disciplined action.
