I have thus told you a mystery, viz., the manner in which a Shudra may become a Brahmana, or that by which a Brahmana falls away from his own pure position and becomes a Shudra, stain of contact with persons born in inferior castes, by abstaining from the acceptance of gifts, and by other acts laid down in the scriptures.
एतत् ते गुह्यमाख्यातं यथा शूद्रो भवेद् द्विजः। ब्राह्मणो वा च्युतो धर्माद् यथा शूद्रत्वमाप्नुते॥
