釋禪波羅蜜次第法門 4.61

4.61

Furthermore, loving-kindness means giving happiness to others; lustful desire is unwholesome, increasing others' afflictions; this is not the path of giving happiness. Contemplating thus, tying the mind to cultivating loving-kindness, if the absorption of loving-kindness arises, it directly treats lustful desire. Why is this? The immeasurable minds are dharmas of the form realm; it is impossible for a mind of lustful desire to arise [in them]. Here, although the affliction does not shift, one shifts contemplation to treat it. Now, taking the single gate of impurity as an analogy, the remaining fourteen gates of dhyāna can all be understood to have these two kinds of shifted treatment.
