俱舍論疏 5.30

5.30

「論曰至名無想定」，類無想異熟釋無想定也。別有二十一、或二十二非色非心不相應行，能令二十二心、心所滅，名無想定。

"The Treatise says... it is called the non-conception attainment": This explains the non-conception attainment by analogy with the maturation of non-conception. There are distinct twenty-one or twenty-two formations not associated with mind that are neither matter nor mind, which are able to cause the twenty-two minds and mental factors to cease, and are called the non-conception attainment.
