Mahavishnu (Devanagari: महाविष्णु) is an aspect of Vishnu, the Absolute which is beyond human comprehension and is beyond all attributes. In Vaishnavite theology, the term is similar to Nirguna Brahman. It is also often used interchangeably with Vishnu to indicate reverence, as the prefix "Maha" exalts the noun to which it is attached.
