Mbh 13.122.1a

"'Bhishma said, "Thus addressed, the holy one replied unto Maitreya, saying 'by good luck, thou art endued with knowledge. By good luck, thy understanding is of this kind! They that are good highly applaud all righteous attributes. That personal beauty and youth and prosperity do not succeed in overwhelming thee is due to good luck. This favour done to thee is due to the kindness of the deities. Listen to me as I discourse to thee upon what is even superior (in efficacy) to gift. Whatever scriptures and religious treatises there are, whatever (righteous) inclinations are observable in the world, they have flowed in their due order, agreeably with the lead of the Vedas, according to their due order. Following them I applaud gift. Thou praisest penances and Vedic lore. Penances are sacred. Penances are the means by which one may acquire the Vedas and heaven also. With the aid of penances and of knowledge, one attains to the highest fruits, we have heard. It is by penances that one destroys one's sins and all else that is evil. It has been heard by us that with whatever purpose in view one undergoes penances, one attains the fruition thereof in consequence of those penances. The same may be said of knowledge. Whatever is difficult to accomplish, whatever is difficult to conquer, what is difficult to attain, and whatever is difficult to cross, can all be achieved with the aid of penances. Of all things, penances are possessed of very superior might. The man who drinks alcohol, or he that takes by force what belongs to others, or he that is guilty of foeticide, or he that violates the bed of his preceptor, succeeds in crossing with the aid of penances. Indeed, one becomes cleansed of all these sins through penances. One possessed of all knowledge and, therefore, having true vision, and an ascetic of whatever kind, are equal. One should always bow unto these two[536]. All men who have the Vedas for their wealth should be worshipped.
