The soul is like a light in this five-cornered room, for the soul perceives feeling, thought, memory, reason, and identity, and identifies itself with them. In reality it is aloof from them; change of feeling or thought does not change the soul. But as the soul cannot see itself, it thinks, by the help of the ego: I am sad, or I am glad, or I remember, or I have forgotten. The soul does none of these things; they are all the workings of the mind; but as the soul does not see itself, it identifies itself with what it sees at this time.
