2.342

又如有一計由自苦身故自惡解脫者，即前第二入諸河中沐浴清淨。或造過惡解脫者，即前第三持狗戒等，食糞飲尿行諸惡事罪惡消滅等。

Regarding 'Moreover, just as there are some who hold that by tormenting their own body they liberate themselves from their own evils': this refers to the second [type] mentioned earlier, purifying oneself by bathing in rivers. Or regarding 'being liberated by committing transgressions and evils': this refers to the third [type] mentioned earlier, keeping the dog precepts and the like, eating feces, drinking urine, and performing all kinds of wicked acts to eliminate sins and evils, and so forth.
