Kshirodakshayi Vishnu
Ksirodakasayi Vishnu is a form of the Hindu god Vishnu. As the Paramatma, he is described to "enter every atom and the heart of all beings as a witness, and gives remembrance, knowledge and forgetfulness”.
In Gauḍīya Vaishnavism, a school of Vaishṇavism, the Sātvata-tantra describes three different forms, or aspects, of Vishnu as Mahavishnu also known as Karnodakshayi Vishnu, Garbhodakśayī-Viṣṇu and Kṣīrodakaśāyī Vishnu Kṣīrodakaśāyī-Viṣṇu resides in the heart of every living creature as a four hand expansion similar to that of Mahāviṣṇu. He is also referred to as the Paramātmā, or super soul. His abode is Vaikunṭha. His personal abode is the Kshira Sagara and he is realised as the Aniruddha expansion of Narayana.
