The yogic tradition is filled with stories of the great yogi Gorakhnath. Some say he lived in the eleventh century, but there are many accounts that date him much earlier. He was a disciple of Matsyendranath, an illustrious yogi in his own right. Such was his level of attainment that Matsyendranath was often venerated as a reincarnation of Shiva or Adiyogi. The lore tells us that Matsyendranath lived for about six hundred years.
