The learned and sages call Shiva by many names —Kshetragya, Prakriti Vyakta, Kalatma etc. The synonyms of Kshetragya and Prakriti are Purusha and Pradhan respectively.The delusionary net of the Prakriti is known as Vyakta (apparent). Kala (time) is the resultant by product of Pradhan and Vyakta. Some sages call Hiranyagarbha (Brahma) as the Purusha and Shiva as Pradhan. They consider Hiranyagarbha to be the creator and Purusha to be the enjoyer. Even these sages are of the opinion that Hiranyagarbho, Pradhan, Purusha and enjoyer are the manifestations of Shiva.
