Q: What are physical ailments? Are they attacks by the hostile forces from outside?
A: There are two factors that have to be considered in the matter. There is what comes from outside and there is what comes from your inner condition. Your inner condition becomes a cause of illness when there is a resistance or revolt in it or when there is some part in you that does not respond to the protection; or even there may be something there that almost willingly and wilfully calls in the adverse forces. It is enough if there is a slight movement of this kind in you; the hostile forces are at once upon you and their attack takes often the form of illness.
