Mahavishnu

Mahavishnu (Devanāgarī : महाविष्णु) is an aspect of Vishnu, the Absolute which is beyond human comprehension and is beyond all attributes. In Gauḍīya Vaishnavism, a school of Vaiṣṇavism, the Sātvata-tantra describes three different forms, or aspects, of Vishnu as Mahavishnu, Garbhodakśayī-Viṣṇu and Kṣīrodakaśāyī Vishnu. The term Mahavishnu is similar to Brahman and Almighty Absolute Supreme Personality of Godhead. This means that the Absolute truth is realized first as Brahman (impersonal aspect) then as Paramatma (personal aspect) and finally as Bhagavan (incarnate perfection). So bhakti (loving devotion) goes to Bhagavan, Krishna (the Avatar of Vishnu, Narayana). In this way, bhakti surpasses even yoga, which is aimed at the Supersoul, Paramatma. Mahavishnu is the Supersoul of all living beings (jivaatmas) in all material universes. It is also often used interchangeably with Vishnu to indicate reverence, as the prefix "Mahā" exalts the noun to which it is attached. It is believed that Adi Parashakti has been created by Maha Vishnu to maintain the Material Universe. So Parashakti is working under the direction of Maha vishnu. So all the Gods including Shiva, Parashakti, Brahma are considered as the Part of Maha Vishnu Expansion.
