It could be some sort of cloudy centre behind your eyes, or the surface of your face, your inner face or just a kind of flavour, it's always just a bit to the side of anything you focus on, it's you as what you are experiencing from, and it's always some such thought, a little thing you hold onto with your even littler hand and that makes all of this awareness, this unbounded spaciousness gather around a point that is the condition for your being here as you. But all of these are just games you play in thought, none of it is needed, can be let go of and nothing goes away, and whoosh!, the space without any you at all.
