The truth is we all want something, anything, or we wouldn't be here. It is our desire that separates us from the Divine. But there's no use trying to pretend we don't want things, cause no one, certainly not God, believes us. Like at an Alcoholic's Anonymous meeting we must raise our hand and say "I want..." For it is better the devil you know.
Once we acknowledge our wants we can harness that energy for the forces of good. I asked a friend once what she wanted to eat, she said "oh anything, I'm not fussy." Whilst it is generally considered good not to be fussy, it is a dangerous game. Maybe it's the fact that we just eat 'anything' that has gotten us into this great, fat, processed, refined, fast food mess. Maybe if we payed a little more attention to what we wanted we might actually eat more broccoli and less hamburgers, because we would know what our body truly and deeply wants rather than just eating what's in front of us or succumbing to our addictions.
So we must practice owning our wants. For if we want nothing we have nothing to sacrifice in the service of others. Want it, and be prepared to give it up anyway. It may be small things at first. Whilst it may feel strange if we aren't used to it, contrary to popular belief it is not selfish. For if each of us were a little happier we'd pull up the whole world with us. It is our service to the world to be happy!
