楞伽阿跋多羅寶經註解 2.207

2.207

"Mahāmati, as for the characteristic of doubt: because they have attained the characteristic of clear vision of the Dharma, and because the previous two kinds of conceptualized views of self have been severed, doubt regarding the Dharma does not arise, nor do they generate the view of a great teacher elsewhere as to whether it is pure or impure; this is called the characteristic of doubt severed by the srotāpanna."
