Understanding of the self only arises in relationship, in watching yourself in relationship to people, ideas, and things; to trees, the earth, and the world around you and within you. Relationship is the mirror in which the self is revealed. Without self-knowledge there is no basis for right thought and action.

No one knows what capacities for doing and suffering he has in himself, until something comes to rouse them to activity: just as in a pond of still water, lying there like a mirror, there is no sign of the roar and thunder with which it can leap from the precipice, and yet remain what it is; or again, rise high in the air as a fountain. When water is as cold as ice, you can have no idea of the latent warmth contained in it.
I envy you going to Oxford: it is the most flower-like time of one's life. One sees the shadow of things in silver mirrors. Later on, one sees the Gorgon's head, and one suffers, because it does not turn one to stone.
