Spiritual Love is born of sorrow. . . . For men love one another with spiritual love only when they have suffered the same sorrow together, when through long days they have ploughed the stony ground buried beneath the common yoke of a common grief. It is then that they know one another and feel one another and feel with one another in their common anguish, and so they pity one another and love one another.

Those who say they believe in God and yet neither love nor fear Him, do not in fact believe in Him but in those who have taught them that God exists. Those who believe that they believe in God, but without any passion in their heart, any anguish of mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God-idea, not in God.

Those faults we do not have, do not bother us.

Love personalizes all that it loves. Only by personalizing it can we fall in love with an idea.

Only in solitude do we find ourselves; and in finding ourselves, we find in ourselves all our brothers in solitude.

To fall into a habit is to begin to cease to be.

Was man made for science, or was science made for man?
