15.161

「順現法受者至後次第熟」者，別釋三定名。順現法受者，現法謂現身，受謂異熟，謂此生造業即於此生受異熟果。生謂眾同分。順次生受者，謂此生造業，次第二生受異熟果。生謂生處。順後次受業者，謂此生造業，從第三生已去乃至多生皆名為後，在第二生後故。於此後位，果非頓起，次第而熟。

Regarding 'That to be experienced in the present life, up to matures successively later': this explains the names of the three determinate ones separately. 'To be experienced in the present life': 'present life' refers to the present bodily existence; 'experience' refers to maturation. It means that creating karma in this life, one experiences the maturation fruit in this very life. 'Birth' means the generic likeness (nikāya-sabhāga). 'To be experienced in the next birth' means that creating karma in this life, one experiences the maturation fruit in the next, second birth. 'Birth' refers to the place of birth. 'Karma to be experienced subsequently' means that creating karma in this life, from the third birth onward, even across many births, are all called 'subsequent', because they are subsequent to the second birth. In these subsequent stages, the fruit does not arise all at once, but matures successively.
