Kanada and the Vaisesika System (opens the original)
Read excerpt
What if I told you one of ancient India’s greatest thinkers was literally nicknamed “the atom-eater”? Kaṇāda — founder of the Vaiśeṣika school — built a systematic, almost scientific account of reality starting from indivisible particles (paramāṇu) centuries before modern chemistry. But he didn’t stop at physics. He mapped all of existence into six categories, argued that understanding reality’s true structure is the path to liberation (mokṣa), and integrated moral law into the very fabric of at
Jaimini and the Mimamsa-Sutra: The Philosophy of Sacred Action (opens the original)
Read excerpt
Most philosophy curriculums stop at Plato and Kant, leaving out one of the most rigorous, sophisticated, and world-altering traditions in human history. Today, we step into the world of Jaimini, an ancient Indian philosopher (4th–2nd century BCE) who asked a question so precise it launched a debate still raging today: What does it mean to act rightly—and how could we ever truly know? In this lecture, we explore Jaimini’s Pūrva-Mīmāṃsā school and his groundbreaking text, the Mīmāṃsā-Sūtra. We’ll
Patanjali and the Yoga-Sutra (opens the original)
Read excerpt
In this lecture, we explore Patañjali’s Yoga-Sūtra — one of the most rigorous philosophies of mind ever produced in the ancient world. What you’ll discover: • Why modern yoga bears almost no resemblance to what Patañjali actually wrote • The shocking truth: only 3 out of 196 aphorisms address physical postures • The core formula: citta-vṛtti-nirodha — yoga as cessation, not exercise • The Sāṃkhya dualism beneath everything: puruṣa (consciousness) vs. prakṛti (matter) • How liberation (kaivalya)
Guatama: Founder of Nyaya- India's Science of Logic and Reasoning. (opens the original)
Read excerpt
How do you know what you know? Not what you believe, but what you actually know with confidence. In this lecture, we explore the life and work of Akṣapāda Gautama, the founder of the Nyāya school—one of the six orthodox schools of Hindu philosophy and ancient India’s most sophisticated system of logic. 📚 In this video, we cover: • Historical context: When and where Gautama lived • The Nyāya Sūtras: Structure and significance • The Four Pramāṇas: Valid means of knowledge (Perception, Inference, C
Badarayana's Vedanta Sutra (opens the original)
Read excerpt
You’ve heard of Plato, Confucius, and Kant. But what about Bādarāyaṇa? He wrote one of the most influential texts in human history—the Vedānta-Sūtra—yet historians know almost nothing about his life. Did he even exist as a single person? Or is “Bādarāyaṇa” actually a code name for an entire school of thought? In this lecture, we peel back the layers of this 5th-century CE mystery. We explore a text so compressed that a three-word sentence can unlock the secrets of the universe—or remain complete
