俱舍論記 27.92

27.92

「初三別緣至無如是能」者，總答。初三神境、天眼、天耳，各別緣色為境界故。修他心通，必先觀色為門入故。修宿住通，漸次憶念前前色相，出胎五位、胎內五位及中有位，十一分位差別不同方得成故，成時能緣昔在某處及種姓等。應知但約分位漸憶，不約剎那。若約剎那向前漸憶，憶半生事即便命終，豈能修至加行成滿？依無色地，無如是能。

On the passage beginning with "The first three individually cognize" up to "lacks such capacity": A general answer. This is because the first three—psychic power, the divine eye, and the divine ear—each individually take matter (rūpa) as their cognitive object. Cultivating the supernormal knowledge of another's mind necessarily requires first contemplating matter as the doorway of entry. Cultivating the supernormal knowledge of past abodes is achieved only after gradually recollecting earlier and earlier material configurations across the differences of the eleven stages—the five stages outside the womb, the five stages within the womb, and the intermediate existence (antarābhava)—and once achieved, it is able to cognize one's past dwelling in a certain place, one's clan, and so forth. One should know that this gradual recollection is only according to developmental stages, not moment by moment. If one were to gradually recollect backward moment by moment, one would exhaust one's lifespan after recollecting the events of half a lifetime; how could one cultivate until the preparatory application is brought to completion? Relying upon the formless levels, one lacks such capacity.
