These are the four lower scales, and belong to the psycho-physiological man.

6. Will perception: Volitional perception, the voluntary taking in of an idea; you can regard or disregard physical pain.

7. Spiritual, entirely conscious apperception: Because it reaches the Higher, self-conscious Manas.

[Apperception means self-perception, conscious action, not as with Leibnitz, but when attention is fixed on the perception.]

Or take Sound:

1. It strikes the ear.

2. Self-perception of the ear.
