What, again, is that austerity (of speech)? That utterance which is true as also not hurtful, and is agreeable and beneficial, is the highest austerity of speech: As for example, the utterance, ‘Be calm, my boy. Practise study and yoga. Thery you will gain the highest.’ Svadhyaya-abhyasanam, the practice of the study of scriptures, as is enjoined; ca eva, as well; ucyate, in said to be; tapah, austerity; vanmayam, of speech.
