Shiva Samhita is one of those rare treatises about which, as usual in Hinduism,we know very little.
This esoteric work is about the Hatha Yoga, and along with Gheranda Samhita and Hatha Yoga Pradipika, forms the three important sources of Hatha Yoga.
This is work on Tantra Shastra.
The authorship and date are unknown.
Some ascribe this to the Seventeenth Century.
Shiva Samhita talks about the complex physiology, names 84 different asanas (only four of which are described in detail), describes five specific types of prana, and provides techniques to regulate them.
