Taittiriya Upanishad 2-9-1 passage "yato vacho nivartanthe.." (words recoil, mind can not grasp...) etc., state the same concept regarding Brahman . The visishtadvaita interpretation is that these passages do not indicate a black hole, but the incompleteness of any statement or thought or concept concerning Brahman. Brahman is these and more. This interpretation is consistent with "sarvam kalvidam brahma". Antaryami Brahmanam of Brihadaranyaka Upanishad passage "yasya prithvi sariram yasya atma sariram" is also interpreted to show that Brahman is not a zero point - "nirvisesha chinmatra" (an entity which has nothing except existence)
