Pronunciation: fàng?xià?yī qiè?zhí niàn
Explanation: There are two kinds of 一***. The first is self-grasping: insisting on something you are obsessed with. Even if you can't get it or it's not suitable, you will continue to hold on to it, which eventually turns into resentment. The second is other attachment: that is, the resentment that arises from insisting on something that one is attached to. Both of these methods should be let go. Only when you let go of resentment can your body and mind be healthy.
