二云所斷之障雖成六品，斷煩惱已欲斷所知。一類緣真，更不別起勝進，方入斷所知道，故十三心真見究竟。

The second [interpretation] says: Although the hindrances to be severed form six grades, having severed the afflictions one wishes to sever the cognitive [hindrance]. Uniformly taking true reality as object, one does not separately generate an advanced path before entering the path that severs the cognitive [hindrance]; therefore thirteen mind-[moments] bring the true path of seeing to completion.
