Gorakshanath (also known as Gorakhnath) was an 11th century Nath yogi and one of the two most important disciples of Matsyendranath, the other being Caurangi. The Nath tradition underwent its greatest expansion during the time of Gorakshanath. He produced a number of writings and even today is considered the greatest of the Naths.
It was Gorakshanath who wrote the first books on Laya Yoga. In India there are many caves, many with temples built over them, where it is said that Gorakshanath spent time in meditation.
