俱舍論頌疏論本 23.48

23.48

釋曰：順決擇分今生起者，必前生起順解脫分。諸有創修順解脫分，極速三生方得解脫，謂初生起順解脫分，第二生起順決擇分，於第三生方得入聖，乃至得阿羅漢也。聲聞極速三生、極遲六十劫，獨覺極速四生、極遲百劫。順解脫分聞思所成，唯散地故，三業為體。

The commentary says: For the factors leading to penetration to arise in this life, one must have given rise to the factors leading to liberation in a previous life. For all who initially cultivate the factors leading to liberation, they attain liberation at the quickest in three lives: that is, in the first life one gives rise to the factors leading to liberation; in the second life one gives rise to the factors leading to penetration; in the third life one is only then able to enter the noble [path] and even attain arhatship. For a śrāvaka, it is at the quickest three lives and at the slowest sixty kalpas; for a pratyekabuddha, it is at the quickest four lives and at the slowest one hundred kalpas. The factors leading to liberation are accomplished through hearing and reflection; because they pertain only to the dispersed stage, they take the three karmas as their essential nature.
