瑜伽論記 4.36

4.36

欲所引中，不說捨者，欲所引捨而非忻樂厭惡欲故而非所斷，不善引捨不善性故正是所斷，故說不同。

In that which is induced by desire, equanimity is not mentioned because the equanimity induced by desire is neither delighted in nor disgusted by desire, and hence is not what is to be severed, whereas the equanimity induced by the unwholesome, because it is of an unwholesome nature, is precisely what is to be severed; thus their treatments are not the same.
