ברכות לד,א

The Rambam explains the statement הרהורי עבירה קשין מעבירה thinking of a sin is worse than the sin itself, because the mind is the main driver of the body. If you destroy the driver, the whole body is destroyed. They say the fish stinks from the head down. The Chovas Halvovas sees not being mechaven to a general who delegates to the rest of the army and then goes on vacation. So they held kavono very important such that they would physically force one to be mechaven. They considered the body doing things without the head as mutiny.
Currently, the RMA in SA O’CH 101,1 says we don’t repeat any davenen because the chances are that the second time he would not be mechaven either, as we are distracted by our worldly problems. There is a joke where someone finished his shmonei esrei and the rebbe came over and gave him a shalom aleichem because his mind was somewhere else and he just came back,
