Mbh 12.215.1b

One should, on the other hand, direct one's mind towards knowledge by such persistent efforts as are sure to succeed.[758] With the aid of the declarations of the Srutis and of persistent efforts calculated to bring success, that Knowledge is sure to flow. One that is desirous of saying good words or observing a religion that is refined of all dross, should utter only truth that is not fraught with any malice or censure. One that is possessed of a sound heart should utter words that are not fraught with dishonesty, that are not harsh, that are not cruel, that are not evil, and that are not characterised by garrulity. The universe is bound in speech. If disposed to renunciation (of all worldly objects) then should one proclaim,[759] which a mind fraught with humility and a cleansed understanding, one's own evil acts.[760] He who betakes himself to action, impelled thereto by propensities fraught with the attribute of Passion, obtains much misery in this world and at last sinks into hell. One should, therefore, practise self-restraint in body, speech, and mind. Ignorant persons bearing the burdens of the world are like robbers laden with their booty of straggling sheep (secreted from herds taken out for pasture). The latter are always regardful of roads that are unfavourable to them (owing to the presence of the king's watch).[761] Indeed, as robbers have to throw away their spoil if they wish for safety, even so should a person cast off all acts dictated by Passion and Darkness if he is to obtain felicity. Without doubt, a person that is without desire, free from the bonds of the world, contented to live in solitude, abstemious in diet, devoted to penances and with senses under control, that has burnt all his sorrows by (the acquisition of) knowledge, that takes a pleasure in practising all the particulars of yoga discipline, and that has a cleansed soul, succeeds, in consequence of his mind being withdrawn into itself, in attaining to Brahma or Emancipation.
