In Sikh mythology, Isar (or Isvar) is mentioned as a Gorakhpanthi yogi who engaged in a spiritual discourse with Guru Nanak at Sumer Mountain. This meeting, as described in Sikh texts like the Miharban Janam Sakhi, involved Isar and a group of Nath ascetics discussing the nature of the Supreme Reality and the true spiritual path.
The dialogue between Guru Nanak and Isar highlights the Sikh emphasis on rejecting ritualistic practices and focusing on devotion to the One Universal Creator. Guru Nanak’s teachings often challenged traditional beliefs, advocating for a direct connection with God through humility, meditation, and righteous living.
