成唯識論述記 7.252

7.252

述曰：自下第三，一期有心、無心三解。此第一師。一期生、死俱無六識，故言「常無」，非少有故。常者，一切時義；「聖教說彼無轉識故」者，即《對法》、《顯揚》、《五蘊》皆言無想無心。此中亦說：第六意識生無想天竟，不起故。雖不定言一期皆無心，然總說生彼無第六識心故，生死無心也。若不爾者，論應分別初後有心，中間無心也。

The Commentary states: From here on is the third: three explanations of whether an entire lifespan is with-mind or without-mind. This is the first master. For the entire lifespan, at both birth and death, there are entirely no six consciousnesses, hence it says “always devoid of,” not having them even for a short time. “Always” has the meaning of at all times. “Because the holy teachings state that it is without evolving consciousnesses”: the *Abhidharma-samuccaya*, *Prakaraṇāryavācā*, and *Pañcaskandhaka* all state that no-thought is without-mind. Here it also states that after being born in the heaven of no-thought, the sixth mental consciousness does not arise. Although they do not explicitly say that the entire lifespan is without-mind, they state generally that one born there lacks the mind of the sixth consciousness; therefore, at birth and death there is no-mind. If it were not so, the treatises should distinguish that the beginning and end have mind, while the middle is without mind.
