6.1.13

tapasā brahmacaryeṇa śamena ca damena ca /
tyāgena satyaśaucābhyāṃ yamena niyamena vā //

13. & 14. By self-denial (austerities), perfect celibacy, control of mind and other organs, charitable gifts, truthfulness, cleanliness, innocence, pious habits, devotion of mind and heart, the wise who know what righteousness is and who are full of faith, rid themselves of their sin however grave, committed in thought, word or deed, as easily as the fire destroys a bush of bamboos.
