成唯識論演祕 7.174

7.174

有義彈云：證圓成時無異忍故。無生忍者，意顯證彼無生境故，名無生忍。證圓成時，惑苦不生，豈籍觀耶？故應說云：觀圓成實非惑苦故。無惑苦生，名為惑苦無生忍也。

An opinion criticizes: Because when realizing the consummate there is no distinct receptivity. One of receptivity to the unarisen [dharmas] is meant to show that because of realizing that unarisen object, it is called receptivity to the unarisen. When realizing the consummate, affliction and suffering do not arise; why would it depend on contemplation? Therefore, one should say: Because contemplating the consummate is not affliction and suffering. The non-arising of affliction and suffering is called receptivity to the non-arising of affliction and suffering.
