One who cares oneself, a man who eats beneficial food means food giving benefit, even if the food is very tasty, he has limited meal. And a man who eats less, meaning not eating at once go but eats in little quantity more than once, that person is in fact to giving treatment by himself. In short, if a person takes beneficial meals in moderate and little quantity he may not fall ill, so he has not to go to any doctor. But a person who is not careful about his meals, he becomes sick and he has to go to a doctor from time to time. Once becoming a sick man (he has to seek refuge of a doctor again and again), for becoming healthy. This should be kept in mind.
