釋禪波羅蜜次第法門 4.61

4.61

復次，慈名與他之樂，貪欲不善，增他煩惱，此非與樂之道。如是思惟，繫心修慈，慈定若發，即治貪欲。何以故？無量心是色界法，不應得有貪欲心生，此則病雖不轉，轉觀治之。今以不淨一門類之，餘十四門禪悉有二種轉治之義可知。

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.
