大般涅槃經義記 4.182

4.182

化次第中，先喻、後合。就說涅槃以為風中，文別有二：第一正說涅槃為風；二「如人不遇風王」已下明涅槃風，思求乃得、不求不得。前中先喻，「如人在海，乘船欲度」喻須風，「人若得順」下明得風益，「若不得」下明不得損。下合顯法，先合須人，「若得值」下合得風益，「若不值」下合不得損。

In the order of transformation, it first gives the simile and then applies it. In speaking of nirvāṇa as the wind, the text has two distinct parts: first, directly speaking of nirvāṇa as the wind; second, from "like a person not encountering the king of winds" below, explaining that the wind of nirvāṇa is attained only through reflection and seeking, and is not attained without seeking. Within the former, it first gives the simile: "like a person in the ocean, boarding a boat and wishing to cross" is a simile for needing the wind; from "if the person gets a favorable [wind]" below, it explains the benefit of getting the wind; from "if he does not get [it]" below, it explains the loss of not getting it. Below, it applies it to reveal the Dharma: first, it matches needing the person; from "if one gets to encounter" below, it matches the benefit of getting the wind; from "if one does not encounter" below, it matches the loss of not getting it.
