Nath Siddhas are the nine saints from Hinduism who attained Mantra Siddhi. The Naths brought to light different systems of tantric practice that were aimed at the transubstantiation of the human body into a divine immortal body.

The North Indian tradition has listed down 9 Naths and 84 Siddhas in its ancestry. Most of these 84 Siddhas appeared in the Buddhist tantric tradition, where it is sometimes said that they practiced Hindu Tantra by day and Buddhist Tantra at night. Central to their methods were the practices of Hatha, Kundalini Yoga and Alchemical Yogas.

Origin of Nath Siddhas
The word "Nath" is derived from the name of Lord Shiva and its literal meaning is "Lord". The tradition of the 9 Nath Siddhas is derived from the flowering of Shaivite Tantra dating back in the 10th century. The Naths are believed to be the descendants of earlier cults including the Pashupatas, Kapalikas and Siddhas.
