Mbh 12.214.2a

"'"Among men, those that are regenerate have been called the foremost; and amongst the regenerate, they that are conversant with the Vedas. These last are regarded as the souls of all living creatures. Indeed, those Brahmanas that are conversant with the Vedas are regarded as all-seeing and omniscient. They are persons who have become conversant with Brahma. As a blind man, without a guide, encounters many difficulties on a road, so has a person destitute of knowledge to encounter many obstacles in the world. For this reason, those that are possessed of knowledge are regarded as superior to the rest. Those that are desirous of acquiring virtue practise diverse kinds of rites according to the dictates of the scriptures. They do not, however, succeed in attaining to Emancipation, all that they gain being those good qualities of which I shall presently speak.[748] Purity of speech, of body, and of mind, forgiveness, truth, steadiness, and intelligence,--these good qualities are displayed by righteous persons observant of both kinds of religion. That which is called Brahmacharya (religion of abstention or yoga) is regarded as the means of attaining to Brahma. That is the foremost of all religions. It is by the practice of that religion that one obtains the highest end (viz., Emancipation). Brahmacharya is divested of all connection with the five vital breaths, mind, understanding, the five senses of perception, and the five senses of action. It is on that account free from all the perceptions that the senses give. It is heard only as a word, and its form, without being seen, can only be conceived. It is a state of existence depending only on the mind. It is free from all connection with the senses. That sinless state should be attained to by the understanding alone.
