Only as a secondary consideration does he hope that some benefit may accrue to himself from the transformed substance as the panacea, the medicina catholica, just as it may to the imperfect bodies, the base or "sick" metals, etc. His attention is not directed to his own salvation through God's grace, but to the liberation of God from the darkness of matter.”

“Man's task is to become conscious of the contents that press upward from the unconscious.”

“Man is much more the victim of his psychic constitution than its inventor.”

“To find out what is truly individual in ourselves, profound reflection is needed; and suddenly we realize how uncommonly difficult the discovery of individuality is.”

“A man who has not passed through the inferno of his passions has never overcome them.”
