“The soul of man is the lamp of God,’ says a wise Jewish proverb. Man is a weak and miserable creature when God’s light is not burning in his soul. But when it burns (and it only burns in souls enlightened by religion), man becomes the most powerful creature in the world. And it cannot be otherwise, for what then works in him is not his own strength, but the strength of God.”

“You cannot lift another soul until you are standing on higher ground than he is. You cannot light a fire in another soul unless it is burning in your own soul.”

“This is the eternal origin of art that a human being confronts a form that wants to become a work through him. Not a figment of his soul but something that appears to the soul and demands the soul's creative power. What is required is a deed that a man does with his whole being..”

“Man's soul has three powers, and God left him prophets for all three: Jewish moralists for his will, Greek philosophers for his mind, and pagan mythmakers for his heart and imagination and feelings. Of course, the latter two are not infallible.”

“I call that man awake who, with conscious knowledge and understanding, can perceive the deep unreasoning powers in his soul, his whole innermost strength, desire and weakness, and knows how to reckon with himself.”

“The metaphor is perhaps the most fruitful power of man. Its efficacy verges on magic, and it seems a tool for creation which God forgot inside one of His creatures when He made him.”
