To keep these ideas at a certain level of generality is the safest course. I mean to say that most of us are familiar with what we mean when we talk about desire. And it’s not the same as want or need, is it. It’s not just a deeper, or stronger, or brighter or heavier type of need. Desire comes from a place in the brain that is not necessarily driven by anything we can talk clearly about. If anything, desire is controlled by the breath, and in turn controls the breath. And that may be some clue to it. We don’t want oxygen, and to say we need oxygen is a bland way of saying that without it, our revels are ended. So as I breath, desire breathes me.
