大般涅槃經義記 10.47

10.47

次解上流。於中，先明退上生下。「流有二」下，從下向上，先舉二流、次列其名。退上善法而生下結，名煩惱流。又斷下結生上煩惱，亦得名為煩惱流也。治道漸增，名為道流。下約道流解上流義。「初至四禪亦復如是」明廣果下上流之義；「復有二」下，明廣果上上流之義。於中有三：一略分二人；二「如是二人一樂」已下，辨因顯果；三「是名」下，結別其相。初段可知。

Next, it explains parinirvāṇa by flowing upward. Within this, it first clarifies retrogressing from the upper to be born in the lower. From "the flows are of two kinds" downward, proceeding from below upward, it first sets forth the two flows and next lists their names. Retrogressing from upper wholesome dharmas to produce lower fetters is called the flow of afflictions. Moreover, severing lower fetters to generate upper afflictions can also be called the flow of afflictions. The gradual increase of the antidote path is called the flow of the path. Below, it explains the meaning of flowing upward in terms of the flow of the path. "From the first to the fourth dhyāna it is likewise" clarifies the meaning of flowing upward below Bṛhatphala; from "there are further two" downward, it clarifies the meaning of flowing upward above Bṛhatphala. Within this, there are three [parts]: 1. briefly dividing into two persons; 2. from "of these two persons, one delights in..." downward, distinguishing the causes to reveal the fruitions; 3. from "this is called" downward, concluding by distinguishing their characteristics. The first section is self-evident.
