The adjective bodily describes something that has to do with your physical self.
Bodily functions include things that happen both inside your body, like digestion and breathing, and outside your body, like walking. If your new kitten scratches your arms, you might say that Mr. Whiskers has caused you bodily harm. In religion, bodily is sometimes used in contrast to "spiritual." As an adverb, this word can be used to mean "in a way that involves someone's body." Your little brother might sleep so soundly that when he falls asleep in the car, you have to carry him bodily into the house.
