成唯識論述記 4.427

4.427

述曰：四立量也。設許長時後位及初位有其五識，即諸轉識有間斷、有轉易，性是不堅，無力一切時執持名色，如何乃說恒與為緣？體非恒故。量云：轉識不能恒持名色；有間、轉故；如聲、風等。《攝論》齊識退還，識若不斷壞，名色得增長不等，皆此中攝。理即互為緣識攝故。

The Commentary states: The fourth part establishes the formal inference. Even if one concedes that in the prolonged subsequent stages and the initial stage there are the five consciousnesses, the evolving consciousnesses have interruption and change; their nature is unsolid, and they lack the power to uphold name and form at all times. How then can they be said to serve constantly as conditions? Because their essence is not constant. The inference is: The evolving consciousnesses cannot constantly uphold name and form; because they are subject to interruption and change; like sound, wind, and so forth. In the Mahāyānasaṃgraha, [the citations concerning] 'turning back at consciousness,' and 'if consciousness does not perish, name and form grow and increase,' are all subsumed herein, for logically it is subsumed under the consciousness that is mutually conditioning.
