The mind commands the body and is instantly obeyed. The mind commands itself and meets resistance. The mind commands the hand to move, and it so easy that one hardly distinguishes the order from its execution. Yet mind is mind and hand is body. The mind orders the mind to will. The recipient of the order is itself, yet it does not perform it.
Saint AugustineWe make ourselves a ladder out of our vices if we trample the vices themselves underfoot.
Saint AugustineLove God and do whatever you please: for the soul trained in love to God will do nothing to offend the One who is Beloved.
