The Early Sessions, Book 2

As far as self and notself are concerned, the unit of self is organized, as you by the inner ego, which directs the whole energy field. The outer ego directs the manipulation of this gestalt in the physical universe. The outer ego is rather more tied to physical properties, and yet it can directly experience inner reality by a change of focus through aligning itself with the inner ego, focusing its energies with the inner rather than the outer senses. This is by far the most advantageous method of experiencing inner reality, because the outer ego is therefore consciously aware of what has been going on, and can use such knowledge in its own sphere."
