俱舍論疏 4.152

4.152

論「已說無慚至謂除前三相」，釋第二對愛、敬相別。與忻相應信，名之為愛，即是愛樂可忻尚法。貪染前境亦名為愛，即是染著愛也。由此愛妻子等，是染著愛；愛師長等，是信愛也。緣滅、道諦忻相應故，亦信亦愛。緣苦、集諦厭相應故，是信非愛。染愛貪故，是愛非信。

On the Śāstra's [words], "Having explained non-shame […] means excluding the first three alternatives": this explains the second pair, the distinction between love (priyatā/preman) and veneration (gaurava). Faith associated with joy is called "love"; that is, delighting in dharmas that are worthy of joy and esteem. Tainted attachment to external objects is also called "love"; that is, the love of stained clinging. Thus, loving one's wife, children, and so forth is the love of stained clinging; loving one's teachers, elders, and so forth is the love of faith. Because [the mind] is associated with joy when taking the truths of cessation and the path as objects, it is both faith and love. Because it is associated with revulsion when taking the truths of suffering and origination as objects, it is faith but not love. Because tainted love is greed, it is love but not faith.
