By living upon only one meal a day, procured by begging, by doing all his acts himself, by going about begging with a human skull in one hand and a staff with a skull on it in another, by becoming a Brahmacharin and always ready for work, by renouncing all malice, by sleeping on the naked earth, by declaring his offence publicly, by doing all this for full twelve years, a person can cleanse himself from the sin of a Brahmanicide.
