Patanjali
c. 2nd century BCE – 4th century CE (disputed)
“How does the movement of the mind obscure the nature of pure consciousness, and how can that movement be stilled?”
Primary Contribution
The Yoga Sutras — 196 aphorisms that constitute the most systematic pre-modern psychology of consciousness in any tradition. Patanjali distinguishes between the Seer (Purusha — pure consciousness, the witness) and the seen (Prakriti — the field of nature, including the mind). The mind's fluctuations (vrittis) create the illusion of identification with what is seen. Yoga — in its original meaning — is the cessation of those fluctuations, not physical postures. His eight-limbed path (Ashtanga Yoga) provides a comprehensive method from ethical conduct through concentration to the highest states of absorption (samadhi). His taxonomy of the samadhi states — savikalpa (with seed/content) and nirvikalpa (seedless/contentless) — provides an experiential map of the territory beyond ordinary mind.
Key Ideas
- Chitta-Vritti-Nirodha: yoga is the cessation of the fluctuations of the mind-field, revealing pure consciousness
- The Eight Limbs (Ashtanga): yama, niyama, asana, pranayama, pratyahara, dharana, dhyana, samadhi — a complete map from ethics to absorption
- Purusha and Prakriti: consciousness is the eternal witness; matter/mind is what is witnessed — suffering arises from confusing the two
- Samadhi taxonomy: savikalpa (absorption with content/seed) → nirvikalpa (seedless absorption) → kaivalya (final isolation of pure awareness)
- Kleshas (afflictions): ignorance, egoism, attachment, aversion, and fear of death — the five root causes of suffering

“Yoga chitta vritti nirodha. — Yoga is the cessation of the fluctuations of the mind-field. Then the Seer abides in its own nature.”
Further Sayings
Legacy & Influence
Patanjali's Yoga Sutras remain the foundational text of contemplative practice across the world. His psychological framework — distinguishing consciousness from its contents — anticipated by two millennia the core insight of phenomenology (Husserl) and the hard problem of consciousness (Chalmers). The eight-limbed path became the structural basis for virtually every systematic meditation tradition. His influence extends through Swami Vivekananda's Raja Yoga (which introduced the Sutras to the West), through the modern mindfulness movement, and into clinical psychology (MBSR, MBCT). The Sutras have been translated into over 40 languages and remain required reading in consciousness studies.
