Actually, the Vaisnava who knows that he is not this body, he does not therefore neglect his body, but he takes very nice care so that he may utilize his body in the service of Krishna. Just like a man may know that he is not his car, so he does not therefore neglect his car, but he will take care of it so it will be able to render service to him. So we must take sufficient care to provide our bodies with its demands, but when disease or other necessary inconveniences arrive, we do not become disturbed because such troubles are simply temporary manifestations.
