Sort of echoing Leed, I feel like contentment is a sort of inner fulfillment and abundance, that "God's in his heaven, all's right with the world". I don't feel like contentment and desire are necessarily opposites. You can feel great satisfaction working to accomplish the things you want in life, and wanting nothing can deteriorate into staleness. Life is always active, always reaching, striving, expressing, growing into itself and becoming itself, and out of a desire we call "God's Will" for its overwhelming power. Love is both contentment and desire.
