+ If your engagement with others is tainted by strong attachment, craving,
+aversion, anger, and so forth, then that form of grasping is undesirable. But
+on the other hand, when you are interacting with other living beings and
+become aware of their needs or suffering or pain, then you need to fully
+engage with that and be compassionate. So there can be positive attachment in
+this sense of active engagement.
+ Buddhist masters have long used the term attachment to describe the quality
+of compassion for others. For example, a verse from Haribhadra’s Clear
+Meaning Commentary refers to compassion that is attached to other living
+beings. And as we have seen, Nagarjuna teaches that attachment for other
+living beings will arise spontaneously in the person who realizes emptiness.
