俱舍論疏 9.37

9.37

論「其有生緣至餘處餘類」，明有定者必令合也，其不定者寄餘類生。此是滿果相別，引同前也。

On the Śāstra's 'If its conditions for birth... in another place, among another class': this clarifies that what is determinate must certainly be brought to assembly, whereas what is indeterminate takes birth dependent on another class. This is the difference in integrating effects (paripūrakaphala); the projecting [karma] is the same as before.
