We have a desire; we chase it, catch it, and consume it. We then need another passion. Our hands are full, but as we grasp for more, we inevitably drop once meaningful pieces of ourselves.

There is a "one-in-one-out" policy when we relate to desire as captured objects. You can clutch them to you but only hold so many; thus, they fall away as you dart about in pursuit.

Or, you can let them pass through you as they arise, enjoying them without possessing them. This is love without attachment or ego making demands or expecting reciprocation. And you are still present and full of enjoyment without the grasping.
