jein.. es ist eher ein spirituelles konzept:
What Is Attachment?
In order for there to be attachment, you need two things -- the attacher, and the thing to which the attacher is attached. In other words, "attachment" requires self-reference, and it requires seeing the object of attachment as separate from oneself.
The Buddha taught that seeing oneself and everything else this way is a delusion. Further, it is a delusion that is the deepest cause of our unhappiness. It is because we mistakenly see ourselves as separate from everything else that we "attach."
Zen teacher John Daido Loori said,
"[A]ccording to the Buddhist point of view, nonattachment is exactly the opposite of separation. You need two things in order to have attachment: the thing you’re attaching to, and the person who’s attaching. In nonattachment, on the other hand, there’s unity. There’s unity because there’s nothing to attach to. If you have unified with the whole universe, there’s nothing outside of you, so the notion of attachment becomes absurd. Who will attach to what?"Because we think we have intrinsic existence within our skin, and what's outside our skin is "everything else," that we go through life grabbing for one thing after another to make us feel safe, or to make us happy.
