Yoga Sutra 1.20 reveals Patanjali’s universal path to samadhi for ordinary practitioners through five sequential stages—śraddhā, vīrya, smṛti, samādhi, and prajñā. Rather than inherited privilege, liberation unfolds through disciplined removal of inner obstructions, allowing dormant yogic samskāras to awaken naturally and culminate in objectless absorption.
This expanded glossary completes the essential vocabulary needed to fully understand Patanjali’s Yoga Sutra, especially the profound teachings of 1.18–1.19. Covering advanced sadhana, post-death paths, psychological pitfalls, and subtle distinctions, it clarifies how abhyasa, vairagya, samskaras, and liberation processes interconnect—revealing the entire spectrum from effort to Kaivalya.
