Desires are good. In fact, they are essential -- they fuel all of existence. It is desires that put the eternal in eternity. When I have a new desire -- for health, friendships, material objects, whatever -- I actually pull life force into my body. It's impossible to live without desires. (Even to have no desires is a desire!)
Further, when I have a new desire, the Universe responds immediately by, in effect, sending the object of my desire toward me. It is then up to me to get into a sufficiently good-feeling place to bring the desire into physical manifestation. I do this by focusing on what I want, not the lack of it.
