In some sense, I must be detached from others in the sense that my behavior is not controlled by what someone else does. Until I am detached from himself, I will never be detached from what others do to that self.
“I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me.” (Galatians 2:20)
As long as I am living for himself, I will be oversensitive, jealous, envious and as a result, always reacting immediately to what others do. The only way to detach yourself from what others do to you is that you first detach yourself from yourself.
I cannot remain at the center – that space now belongs to God.
