Just as in earthly life lovers long for the moment when they are able to breathe forth their love for each other, to let their souls blend in a soft whisper, so the mystic longs for the moment when in prayer he can, as it were, creep into God.

Mysticism and exaggeration go together. A mystic must not fear ridicule if he is to push all the way to the limits of humility or the limits of delight.

All mystics speak the same language, for they come from the same country.

What does mysticism really mean? It means the way to attain knowledge. It's close to philosophy, except in philosophy you go horizontally while in mysticism you go vertically.
