Explanation:

Purushasukta is hymn 10.90 of the Rigveda, dedicated to the Purusha, the "Cosmic Being".One version of the suktam has 16 verses, 15 in the anu??ubh meter, and the final one in the tri??ubh meter. Another version of the suktam consists of 24 verses with the first 18 mantras designated as the Purva-narayana and the later portion termed as the Uttara-narayana probably in honour of Rishi Narayana. Some scholars state that some verses of Purushasukta are later interpolations to the Rigveda
