Hiranyagarbha is mentioned in ancient literature and verse. The "Rig Veda," for example, contains a hymn to Hiranyagarbha that Hindus still chant in their daily rituals, in which he is referred to as the Supreme Being. The epic narrative, "Mahabharata," cites Hiranyagarbha as the one who is glorified in Vedic verses and taught in yoga literature. The Upanishads call him the Supreme Existence, or Brahman. In this regard, Hiranyagarbha is also a name for Brahma in classical Puranic Hinduism because he was born from a golden egg.
While Hiranyagarbha appears most often as a deity or deity in human form, it is possible that a human teacher with the name once existed. Rishi Vashishtha, one of the most prominent Vedic sage-seers, is said to be the main disciple of Hiranyagarbha.
