The name Vallabha gave to the theology underlying his Puṣṭimārga. Denying the Advaita reading of māyā, Vallabha maintains the reality of the world, which he sees as identical with Kṛṣṇa (= brahman (neut.). Individuals too are ultimately parts of Kṛṣṇa, but they remain ignorant of their true nature, and so subject to rebirth, unless freed by his grace. This is facilitated by the disinterested service (sevā) of, and complete surrender to, the deity in temple bhakti. Śuddhādvaita is claimed to be partially derived from the no longer extant works of the Vedāntin, Viṣṇusvāmin.
