Krishna-Swaipayana Vyasa, The Mahabharat — Section CLXIV
“ Sitting by the side of his mother, Yudhishthira asked her in private, 'What is the task, O mother, that Bhima of terrible prowess seeketh to accomplish? Doth he do so at thy command or of his own accord?' Kunti replied, 'Bhima, that chastiser of foes, will at my command, do this great deed for the good of the Brahmana and the liberation of this town.'"Yudhishthira said, 'What rash act hast thou done, O mother! It is difficult of being performed and almost amounteth to suicide! The learned never applaud the abandonment of one's own child. ”
