Mbh 3.199.11d

Giving up dry disputation, have recourse to Sruti and Smriti, and seek thou, with the aid of thy reason, the knowledge of the Undecaying One that is without a second. One’s search (after this knowledge) becometh futile from defect of means. Therefore, should one carefully strive to obtain that knowledge by aid of the Vedas. The Vedas are the Supreme Soul; they are His body; they are the Truth. The soul that is bounded by the animal organism is incompetent to know Him in whom all the Vedas merge. That Supreme Soul, however, is capable of being known by the pure intellect. The existence of the gods as stated in the Vedas, the efficacy of acts, and the capacity for action of being furnished with bodies, are noticeable in every Yuga. Independence of these and annihilation are to be sought from purity of the senses. Therefore, the suspension of the function of the senses is the true fasting. One may attain to heaven by asceticism, one may obtain objects of enjoyment by the practice of charity and may have his sins purged off by ablutions in tirthas. But complete emancipation cannot be had except by knowledge.’”
