“Hatha Yoga Pradipika” is a Sanskrit text about hatha yoga, supposedly dated to the 15th century. The author is Swami Swatmarama, a follower of Swami Goraksha. It is the oldest surviving classic text of hatha yoga. The other two texts dating from a later period are Gheranda Samhita and Siva Samhita. It is a collection of early sources with the addition of Swatmarama’s own yoga practice. There are many translations of this text – including into Russian. The text was written in the framework of the Hindu philosophical school of yoga and is dedicated to Shiva, who, according to the Hindu tradition, passed on the secret knowledge of hatha yoga to his divine wife Parvati. In general, the text consists of 390 stanzas, and is divided into four parts: The first lists the pit (restraint in behavior), niyama (observed restrictions), asanas, and nutrition. The second describes pranayama and shatkarmas (practices of internal purification). The third tells about the wise, bandhas (“castles”), nadi (channels in the subtle body of a person through which prana flows), and kundalini energy. The fourth describes Pratyahara, Dharana, Dhyana, and Samadhi. Read the On-line book.
