There are many people who reach their conclusions about life like schoolboys: they cheat their master by copying the answer out of a book without having worked the sum out for themselves.

Father in Heaven! When the thought of thee wakes in our hearts let it not awaken like a frightened bird that flies about in dismay, but like a child waking from its sleep with a heavenly smile.

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.

One must not think slightingly of the paradoxical…for the paradox is the source of the thinker’s passion, and the thinker without a paradox is like a lover without feeling: a paltry mediocrity.

To defend something is always to discredit it. Let a man have a warehouse full of gold, let him be willing to give away a ducat to every one of the poor - but let him also be stupid enough to begin this charitable undertaking of his with a defense in which he offers three good reasons in justification; and it will almost come to the point of people finding it doubtful whether indeed he is doing something good. But now for Christianity. Yes, the person who defends that has never believed in it.

To cheat oneself out of love is the most terrible deception; it is an eternal loss for which there is no reparation, either in time or in eternity.
