SB 11.3.36 — Neither the mind nor the faculties of speech, sight, intelligence, the life air or any of the senses are capable of penetrating that Supreme Truth, any more than small sparks can affect the original fire from which they are generated. Not even the authoritative language of the Vedas can perfectly describe the Supreme Truth, since the Vedas themselves disclaim the possibility that the Truth can be expressed by words. But through indirect reference the Vedic sound does serve as evidence of the Supreme Truth, since without the existence of that Supreme Truth the various restrictions found in the Vedas would have no ultimate purpose.
