十門第五解其流義，即決擇第三卷中三種流義。基云：初等流流復有四種者，此中初二，不離前異熟長養二種，即一物，其本性等流，準下文除根色餘三種流明擇根塵亦有本性流，相易可知。即唯外五塵其五根中根及長養皆可變壞亦得是第二等流。二等流寬遍異熟等也，前念滅後念生名曰等流流，其內根等得異熟長養名餘外境，唯有本性變易二流，變易流準義通本性報養三種，初一念生時名異熟流，第二念以去相續異熟流此通假實異熟。

In the five explanations of the ten gates, the meaning of 'flux' is explained; this refers to the three kinds of flux in fascicle 3 of the Viniścayasaṃgrahaṇī. Ji says, "Regarding 'the initial flux of equal outflow having four kinds': here the first two are not separate from the previous two kinds, fruition and nourishment, being the very same entity. As for its fundamental-nature equal outflow: according to the subsequent text, setting aside sense-faculty form, the remaining three kinds of flux clarify the discerned faculties and objects as also having fundamental-nature flux, whose characteristics are easily known. That is to say, only the external five sense objects, and within the five faculties the faculties and their nourished [forms], can all change and deteriorate, and can thus also be the second equal outflow. The second equal outflow broadly encompasses fruition and so forth; the cessation of a previous moment and the arising of a subsequent moment is called the flux of equal outflow. The internal faculties and so forth obtain fruition and nourishment, called the remaining external objects; they possess only the two fluxes of fundamental nature and change. The flux of change, according to its meaning, extends to the three kinds: fundamental nature, retribution, and nourishment. The time when the first single moment arises is called the flux of fruition; from the second moment onward, it is the continuous flux of fruition; this extends to both provisional and real fruition.
