Thoughts are the shadows of our feelings - always darker, emptier and simpler.

He who cannot give anything away cannot feel anything either.

Thoughts are the shadows of our sensations -- always darker, emptier, simpler than these.

Thoughts that come with doves' footsteps guide the world.

All truly great thoughts are conceived by walking.

One hears but one does not seek; one takes -- one does not ask who gives; a thought flashes up like lightning, it comes of necessity and unfalteringly formed.
