Shiva Samhita (IAST: śivasaṃhitā, also Siva Samhita, meaning “Shiva’s Compendium”) is a Sanskrit text on yoga, written by an unknown author
The text is addressed by the Hindu god Shiva to his consort Parvati
The text consists of five chapters, with the first chapter a treatise that summarizes nondual Vedanta (Advaita Vedanta) philosophy with influences from the Sri Vidya school of South India
The remaining chapters discuss yoga, the importance of a guru (teacher) to a student, various asanas, mudras and siddhis (powers) attainable with yoga and tantra
The Shiva Samhita is one of three major surviving classical treatises on hatha yoga, the other two being Gheranda Samhita and Hatha Yoga Pradipika
It is considered the most comprehensive treatise on hatha yoga, one that recommends that all householders practice and benefit from yoga
Over a dozen variant manuscripts of the text are known, and a critical edition of the text was published in 1999 by Kaivalya Dham Yoga Research Institute
