又善生經云。有二因緣失菩薩戒。一者退菩提心。二者得上惡心。離是二因緣。乃至他世。地獄畜生餓鬼之中。終不失戒。若於後世更受菩薩戒時。不名新得。名為開示瑩淨。

Furthermore, the Shansheng jing states: 'There are two causes and conditions for losing the bodhisattva precepts: first, retrogressing from the bodhicitta; second, obtaining a supreme evil mind. Free from these two causes and conditions, even into other lives, among the hells, beasts, or hungry ghosts, one never loses the precepts. If in a later life one receives the bodhisattva precepts again, it is not called gaining them anew, but is called revealing and purifying them.'
