Gifted with the power of his divine father, he soared through the heavens toward the sun. Vāyu went with him, covering him with a cool breeze so that he would not be burned by the sun. The sun-god also withheld his blazing rays as he understood that Hanumān was a great servant of Viṣṇu who would later assist Him on earth.
In Patala, Hanuman discovers that to kill Mahiravana, he must extinguish five lamps. Hanuman assumes the Panchamukha or five-faced form of Sri Varaha facing north, Sri Narasimha facing south, Sri Garuda facing west, Sri Hayagriva facing the sky and his own facing the east, and blows out the lamps. Hanuman then rescues Rama and Lakshmana. Afterwards, Rama asks Hanuman to crown Makardhwaja king of Patala. Hanuman then instructs Makardhwaja to rule Patala with justice and wisdom.
SACRED TEXT of Buddhism. Hayagriva is the easiest to identify of all the Dharmapalas, by the horse's head in his hair. He originated from Hinduism where he was one of the manifestations of Vishnu. In Buddhism he is sometimes viewed as an incarnation of the Dhyani Buddhas Amithaba or Aksobhya. Hayagriva is the guardian of the sacred texts who scares his enemies away with his whinnying.
