Mbh 5.42.10a

“Sanat-sujata said, ‘Those regenerate persons that take pride in their Yoga practices, like strong men in their own strength, departing hence, shine in the region of Brahman. Those regenerate persons that proudly exert in performing sacrifices and other Vedic rites, as the fruit of that knowledge which is theirs, in consequence of those acts, freed from this world, proceed to that region which is the abode of the deities. There are others, again, conversant with the Vedas, who are of opinion that the performance of the sacrifices and rites (ordained by the Vedas) is obligatory (their non-performance being sinful). Wedded to external forms, though seeking the development of the inner self (for they practise these rites for only virtue’s sake and not for the accomplishment of particular aims), these persons should not be regarded very highly (although some respect should be theirs). Wherever, again, food and drink worthy of a Brahmana are abundant, like grass and reeds in a spot during the rainy season, there should the Yogin seek for his livelihood (without afflicting the householder of scanty means); by no means should he afflict his own self by hunger and thirst. In a place, where there may be both inconvenience and danger to one, for one’s aversion, to disclose one’s superiority, he that doth not proclaim his superiority is better than he that doth. The food offered by that person who is not pained at the sight of another disclosing his superiority, and who never eateth without offering the prescribed share to Brahmanas and guests, is approved by the righteous. As a dog oftentimes devoureth its own evacuations to its injury, so those Yogins devour their own vomit who procure their livelihood by disclosing their pre-eminence. The wise know him for a Brahmana, who, living in the midst of kindred, wishes his religious practices to remain always unknown to them.
