Scholars describe this philosophy as built on the foundation of non-dualism in the Upanishads, and term it as "Advaitic Theism". This term combines the seemingly contradictory beliefs of a personal God that can be worshiped with a God that is immanent in creation and in one's own self. God in this philosophy is within and is not different from the individual self, states Sheridan, and transcends the limitations of specificity and temporality. Sheridan also describes Advaitic Theism as a "both/and" solution for the questions of whether God is transcendent or immanent, and credits the Bhāgavata with a 'truly creative religious moment' for introducing this philosophy. The text suggests that God Vishnu and the soul (atman) in all beings is one in quality (nirguna).
