Purusha sukta (IAST , Devanāgarī पुरुषसूक्तम्) is hymn 10.90 of the Rigveda, dedicated to the Purusha, the Cosmic Being. Author Steven Rosen says, The Bhagavata Purana and the Mahabharata boldly proclaim Vishnu as ultimate Purusha described in Purusha Sukta prayer. According to Indologist W. Norman Brown, The verses of Purusha Sukta are definitely a reference to Vishnu, who, through his three steps, is all pervading (i.e. he spreads in all directions).
