俱舍論疏 6.150

6.150

The treatise says: "The masters of the *Vibhāṣā* [...] is called the maturation cause." This cites the *Vibhāṣā* to explain the rationale for designating this name in contrast to the other five causes. According to this rationale, the name "maturation" (vipāka) extends generally to the time when fruits obtained from all six causes are matured, which are all called "maturation." But this maturation cause alone is called "maturation" (vipāka) in the sense of maturing into a different class (vijātīya). The other causes do not mature solely into a different class, so they are not called "maturation".
