Mahabharata Anushasna Parva Chapter 151:2

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 151:2 They are fully aware of the distinctions between what is superior and what is inferior. They it is who attain to the highest end. Freed from all attachments, cleansed of all sins, transcending all pairs of opposites (such as heat and cold, happiness and misery, etc.), they are unconnected with all worldly things. Deserving of every honour, they are always held in great esteem by persons endued with knowledge and high souls. They cast equal eyes on sandal-paste and filth or dirt, on what is food and what is not food. They see with an equal eye their brown vestments of coarse cloth and fabrics of silk and animal skins. They would live for many days together without eating any food, and dry up their limbs by such abstention from all sustenance. They devote themselves earnestly to the study of the Vedas, restraining their senses. They would make gods of those that are not gods, and not gods of those that are gods. Enraged, they can create other worlds and other Regents of the worlds than those that exist. Through the course of those high-souled ones, the ocean became so saline as to be undrinkable. The fire of their wrath yet burns in the forest of Dandaka, unquenched by time. They are the gods of the gods, and the cause of all cause. They are the authority of all authorities. What man of intelligence and wisdom is there that would seek to humiliate them? Amongst them the young and the old all deserve honours. They honour one another (not in consequence of distinctions of age but) in consequence of distinctions in respect of penances and knowledge. Even the Brahmana that is destitute of knowledge is a god and is a high instrument for cleansing others. He amongst them, then, that is possessed of knowledge is a much higher god and like unto the ocean when full (to the brim). Learned or unlearned, Brahmana is always a high deity. Sanctified or unsanctified (with the aid of Mantras), Fire is ever a great deity. A blazing fire even when it burns on a crematorium, is not regarded as tainted in consequence of the character of the spot whereon it burns. Clarified butter looks beautiful whether kept on the sacrificial altar or in a chamber. So, if a Brahmana be always engaged in evil acts, he is still to be regarded as deserving of honour. Indeed, know that the Brahmana is always a high deity.
