What is Narayana sukta?

"Whatever all this universe is, seen or heard of—pervading all this, from inside and outside alike, stands supreme the Eternal Divine Being.

The Narayana Sukta or Narayana Suktam is a hymn propitiating the Supreme Deity-Narayana in Yajurveda. Some commentators see it as a mystical appendix to the Purusha Sukta. Narayana, in Hinduism, is considered as the Supreme Truth , the thousand-headed, thousand-eyed, and thousand-limbed creator and this hymn is recited to worship Narayana, the universal Self which is identified with the Brahma , Vishnu and Shiva , who are aspects of the Supreme Lord and not the different deities.
