俱舍論疏 10.68

10.68

論「無明觸中至共相應故」，此明第二愛、恚觸也。一切染觸名無明觸，一切染中愛、恚數行，故於染中別標此二。

On the Śāstra's statement: "Among contacts of ignorance ... because of mutual association": this explains the second set: contacts of attachment and aversion. All defiled contacts are called contacts of ignorance; and among all defilements, attachment and aversion arise frequently, so these two are singled out within defilements.
