The Mahabharata of Krishna-Dwaipayana Vyasa…
“ Where, O slayer of Madhu, words, good or bad, are of the same effect, no wise man would spend his breath for nothing, like a singer before the deaf. As a Brahmana before a conclave of Chandalas, thy words, O Madhava, would command no respect among those ignorant and wicked wretches that have no reverence for all that deserveth reverence. Foolish, as long as he hath strength, he will never obey thy counsels. Whatever words thou mayest speak to him will be perfectly futile. ”
