Where is this ‘Self’?

“When we can’t find a self within or outside of these parts, we may then conclude that the self is that which is aware of all of these things—the knower or mind. But when we look for the mind, we can’t find any shape, or color, or form. This mind that we identify as the self, which we could call ego-mind, controls everything we do. Yet it can’t actually be found—which is somewhat spooky, as if a ghost were managing our home. The house seems to be empty, but all the housework has been done. The bed has been made, our shoes have been polished, the tea has been poured, and the breakfast has been cooked.” ― Dzigar Kongtrül III
