“The mind commands the body and it obeys. The mind orders itself and meets resistance.”

“The mind commands the body and is instantly obeyed. The mind commands itself and meets resistance.”

“The mind commands the body, and obedience is instant; the mind commands itself and meets resistance. The mind tells the hand to move, and all goes so smoothly that it is hard to distinguish the command from its execution. Yet the mind is the mind, and the hand is a body. The mind tells the mind to will; one is the same as the other, and yet it does not do what it is told.”

“The body is the servant of the mind. It obeys the operations of the mind, whether they be deliberately chosen or automatically expressed.”

“Obscenity only comes in when the mind despises and fears the body, and the body hates and resists the mind.”

“Having a body is in itself the greatest threat to the mind... The body encloses the mind in a fortress; before long the mind is besieged on all sides, and in the end the mind has to give itself up.”
