The later verses of Vasudeva Upanisad describe meditation on Vasudeva, as a form of Yoga. The yogin, asserts the text, should look at his inner most self, Atman as Vasudeva. This goal of meditation, and methodology of worship, is found in Pancaratra Agamas, Puranas and other texts of the Vaishnavism tradition. These texts, states Srinivaschari, assert that Sat (Truth), Atman and Upanishadic concept of Brahman denote the Vedantic metaphysics of Ultimate Reality, and declare all three to be synonymous with Vasudeva. The term Vasudeva itself is synonymous with Vishnu and Vasudeva.
