Holding in his hand a yak-tail and an earthen pot, a sinner should go about, giving a publicity to his sin. He should every day beg of only seven families, and live upon what may thus be got. By doing this for twelve days he may be purified of his sin. He who cannot hold in his hand the yak-tail while practising this vow should become a mendicant (as stated above) for one whole year.
