2.463

第四業位中，由軟不善故，生傍生中等者，十地經說：中品生畜生，下品生餓鬼。與此不同，鬼有二種：一、福德；二、薄福。此據薄福故中品，彼據福德故下品，亦不相違。現在所起名生位業；過去曾造之業，已生已滅但有業種，名習氣位業。

In the fourth, on the stages of karma: 'Due to weak unwholesome [karma], one is born among animals', and so on. The Daśabhūmika Sūtra states: the middling grade leads to birth as an animal, and the lower grade leads to birth as a hungry ghost. This differs from that. Ghosts are of two kinds: 1. those with merit; 2. those of meager merit. Here it speaks from the standpoint of those of meager merit, hence the middling grade; that speaks from the standpoint of those with merit, hence the lower grade; thus they do not conflict. Karma that arises in the present is called karma in the stage of arising; karma that was performed in the past, having arisen and ceased, leaving only karmic seeds, is called karma in the stage of karmic impressions (vāsanā).
