成唯識論述記 7.254

7.254

述曰：《瑜伽》第十說言：「問：於一切生處，及三摩鉢底中，皆有一切支現行可得耶？答：不可得。謂無想天、滅盡定、無想定中，唯有色支可得，非無色支。生無色界，唯無色支可得，非有色支」。此依六識，故知彼處，一期無心。

The Commentary states: The tenth fascicle of the *Yogācārabhūmi* states: “Question: In all rebirth states and in samāpattis, are all constituents apprehended in active operation? Answer: They are not apprehended. In the heaven of no-thought, the cessation attainment, and the attainment of no-thought, only material constituents are apprehended, not immaterial constituents. In birth in the immaterial realm, only immaterial constituents are apprehended, not material constituents.” This is said in reliance on the six consciousnesses; hence we know that in that place, an entire lifespan is without mind.
