“A concentrated mind and a sitting body make for better prayer than a kneeling body and a mind half asleep.”

“Reading is to the mind what exercise is to the body and prayer is to the soul.”

“They say that the prospect of being hanged in the morning concentrates a man's mind wonderfully; unfortunately, what the mind inevitably concentrates on is that, in the morning, it will be in a body that is going to be hanged.”

“The country would be far better if the population were half as interested in keeping their minds in as good condition as they tried to keep their bodies.”

“If the mind's not strong, the body acts weak, even if it's not. If the mind says it's too cold or too rainy or too windy to run, the body will be more than happy to agree. If the mind says it would be better to rest or recover or cut practice, the body will be glad to oblige.”

“It is the mind that makes the body.”
