Shiva Samhita is a Sanskrit text on yoga, written by an unknown author. The text is addressed by the Hindu ascetic Shiva to his consort Parvati. The text consists of five chapters, with the first chapter a treatise that summarizes nondual 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 teaches four asanas, one of them, Paschimottanasana, for the first time.
