首楞嚴義疏注經 8.364

8.364

二、正感果相。根境兩具，故云二習。能觸所觸，皆是我心互相熏習，結成婬業，以於欲境起顛倒心，生自他樂想。因此業種，後感其報，從其能觸現地獄身，從其所觸現諸苦具，皆是自業所熏，分其二習自相刑害耳。他皆倣此。

Second, the direct manifestation of the retribution. Because both faculty and object are present, they are called 'two habits'. Both the touching agent and the touched object are our own mind perfuming each other, cementing into lustful karma; through giving rise to an inverted mind regarding objects of desire, one produces thoughts of pleasure for self and other. Due to this karmic seed, later when the retribution is experienced, the body in hell manifests from the touching agent, and the instruments of suffering manifest from the touched object. All are perfumed by personal karma, separating into two habits that inflict mutual harm. The others are all modeled on this.
