Mbh 12.270.1a

"'"Kapila said, 'The Vedas are regarded as authoritative by all. People never disregard them. Brahma is of two kinds, viz., Brahma as represented by sound, and Brahma as Supreme (and intangible).[1256] One conversant with Brahma represented by sound succeeds in attaining to Supreme Brahma. Commencing with the rites of Garbhadhana, that body which the sire creates with the aid of Vedic mantras is cleansed (after birth) by Vedic mantras.[1257] When the body has been cleansed with purificatory rites (performed with the aid of Vedic mantras), the owner thereof comes to be called a Brahmana and becomes a vessel fit for receiving knowledge of Brahma. Know that the reward of acts is purity of heart which only leads to Emancipation. I shall presently speak to thee of that. Whether purity of heart has been attained or not (by performance of acts) is what can be known to the person himself who has attained it. It can never be known with the aid of either the Vedas or inference. They that cherish no expectation, that discard every kind of wealth by not storing anything for future use, that are not covetous, and that are free from every kind of affection and aversion, perform sacrifices because of the conviction that their performance is a duty. To make gifts unto deserving persons is the end (right use) of all wealth. Never addicted at any time to sinful acts, observant of those rites that have been laid down in the Vedas, capable of crowning all their wishes with fruition, endued with certain conclusions through pure knowledge, never giving way to wrath,--never indulging in envy, free from pride and malice, firm in Yoga,[1258] of unstained birth, unstained conduct, and unstained learning, devoted to the good of all creatures, there were in days of yore many men, leading lives of domesticity and thoroughly devoted to their own duties, there were many kings also of the same qualifications, devoted to Yoga (like Janaka, etc.)
