俱舍論疏 8.168

8.168

「論曰至處必無間」，引穀等為例破。現見穀等相續轉法，從子至芽乃至果實中間無斷，故知死、生二有中間亦無斷也。

On the passage from "The treatise says" to "the place must be uninterrupted": It refutes them by citing grain and the like as an analogy. The continuum of grain and the like is directly seen to proceed from seed to sprout up to the fruit without interruption in between; therefore we know that between the two existences of death and birth, there is also no interruption.
