Srinivasa writes the Hataratnavali to clarify Hatha yoga for those confused by conflicting views and ignorant of Raja yoga. He classifies yoga into four types—Mantra, Laya, Raja, and Hatha—intended to grant all siddhis. The work defines Mahayoga as mind restraint and Laya yoga as the complete absorption of Chitta. Laya yoga is achieved through specific physical actions and concentration on Mrityunjaya, though Nadanusandhana is preferred. Laya means forgetting experience, not sensory return. Rajayoga eliminates sensory objects, mental modification, and time. Without Rajayoga, Hatha practices are useless; with it, they succeed. The two are interdependent. Mantrayoga synthesizes mind and breath. The text outlines Hatha Yoga’s path to liberation by unifying solar and lunar energies. It mandates secret purificatory practices, specifically detailing Cakri Karma to remove abdominal ailments. Practitioners must control breath to attain Rajayoga, maintain dietary restrictions initially, and diligently practice regardless of age or health status to achieve success in all yogas. The text prioritizes Cakri Karma for success in all actions. A wise person practices kumbhakas to purify the nadi group, allowing prana to pierce the susumna opening and achieve the steady mind state called manonmani. Experts use eight specific kumbhakas to reach this goal.
