One who lets go of or leaves something is a detached person. And although one who has been abandoned may be called a detached person, what is important in this usage is the fact that one has to leave and turn away from what one wishes to be detached from. …

Note, then, that I am not in any way to seek my own or to think that I can please God. The word “mine” includes my honor, my advantage, my hurt, my desire, my displeasure, my reward, suffering, life, death, sadness, joy, and everything that might affect a person – be it in external goods, or in things that affect the body or the inner being, such as intellect, willpower, and desires. Everything to which ego may cling must leave me and fall off, if I am to be detached. 

Nowhere other than in God will a person be content.
