The mind's capacity is limitless, and its manifestations are inexhaustible. Seeing forms with your eyes, hearing sounds with your ears, smelling odors with your nose, tasting flavors with your tongue, every movement or state is all your mind.
There is a certain frame of mind to which a cemetery is, if not an antidote, at least an alleviation. If you are in a fit of the blues, go nowhere else.
Live for an ideal, and that one ideal alone. Let it be so great, so strong, that there may be nothing else left in the mind; no place for anything else, no time for anything else.
