If the Brahmana, when hard-pressed for a living, performs the duties of either the Kshatriya or the Vaishya, he does not fall off from virtue. When, however, the Brahmana performs the duties of the lowest order, then does he certainly fall off.
क्षत्रधर्मा वैश्यधर्मा नावृत्तिः पतते द्विजः। शूद्रधर्मा यदा तु स्यात् तदा पतति वै द्विजः॥
