第二。（迦留陀夷以佛制前戒，便伺女人將入房，手捉捫摩故制。）戒名中。能所合標，別餘境故。

The second [saṃghāvaśeṣa]. (Because the Buddha instituted the previous precept, Udāyin waited for a woman about to enter a room, seized and stroked her with his hand, and therefore it was instituted.) In the name of the precept: the agent and the object are designated together to distinguish it from other objects.
