Now, that doesn't mean Krishna is limited to only sixty-four qualities in Gaudiya Vaishnavism. There are actually infinite qualities of the Lord and the qualities apart from the ones stated above, are indescribable as the Gaudiya Vaishnava definition of the term "Saguna Brahman" states (Brahman comprising of infinite auspicious/positive qualities).
