Mbh 12.263.4

"'"Tuladhara said, 'Sometimes sacrifices performed by some persons do not become sacrifices (in consequence of the absence of faith of those that perform them). These men, it should be said, are not worthy of performing any sacrifice (internal or external). As regards the faithful, however, only one thing, viz., the cow, is fit for upholding all sacrifices by means of full libations of clarified butter, milk, and curds, the hair at end of her tail, her horns, and her hoofs.[1185] (The Vedas declare that sacrifices cannot be performed by an unmarried man). In performing sacrifices, however, according to the mode I have pointed out (viz., by abstaining from slaughter of animals and dedicating only clarified butter, etc.), one may make Faith one's wedded wife, for dedicating such (innocent) offerings to the deities. By duly reverencing such sacrifices, one is sure to attain to Brahma.[1186] To the exclusion of all animals (which are certainly unclean as offering in sacrifices), the rice-ball is a worthy offering in sacrifices. All rivers are as sacred as the Saraswati, and all mountains are sacred. O Jajali, the Soul is itself a Tirtha. Do not wander about on the earth for visiting sacred places. A person, by observing these duties (that I have spoken of and that do not involve injury to other creatures), and by seeking the acquisition of merit agreeably to his own ability, certainly succeeds in obtaining blessed regions hereafter.'"[1187]
