A wooden chair on a bonfire. Flames lap at the frame, a leg falls into the ash, then the whole frame collapses. At what point is it no longer a chair?
Settle first. Let the body be heavy and relaxed, filled with bright awareness. Then bring forward your usual sense of self. Where do you locate it? Behind the eyes, in the heart, somewhere just above the body?
Now, lightly, as an experiment, let your right leg vanish into open space and be replaced by a whole new one. Then the left. The arms. The heart. An eye of a different colour. Half the brain, then all of it. Are you still you?
Where exactly are you?
