Vira Simhavaloka 104.1

Next, according to karmavipaka (fruit of past deeds), the text gives the cause of impotence, and its remedy. The text says that a man who lived by trading in women may become impotent. So may one who broke his vow with a chandala (an outcaste, in the old social order) woman. So may one who wronged a maiden. So may one who tore a woman's private parts with a finger or the like during union. His prayashchitta (making amends) is as already told. To ease that sin, he should keep two chandrayana (moon-phase fast) fasts. He should give a cow and gold.
