“Very few people believe in the devil these days, which suits the devil very well. He is always helping to circulate the news of his own death. The essence of God is existence, and He defines Himself as: 'I am Who am.' The essence of the devil is the lie, and he defines himself as: 'I am who am not.' Satan has very little trouble with those who do not believe in him; they are already on his side.”

“He who exalts himself will be humbled; He who humbles himself will be exalted....”

“He who knows others is wise; he who knows himself is enlightened.”

“He who knows other men is discerning;he who knows himself is intelligent.He who overcomes others is strong;he who overcomes himself is mighty.He who is satisfied with his lot is rich;he who goes on acting with energy has a (firm) will. He who does not fail in the requirements of his position, continues long;he who dies and yet does not perish, has longevity.”
