Pursuing fasting on certain days in the name of rituals is good for health. This was made in practice only to keep the body fit as we do eat many items irrespective of taste either on an official outing or personal outing. During festivals, we do eat different tasty items. Because of such eating, our stomach may be in disorder. To make up our stomach we do fasting and that too if we do the same in the name of God it is good to mind also as our entire mind concentrated towards God. Everything the rituals designed by our elders to meet out our body as well mind control only.
During the fasting days, we should get away from onion, garlic, non-veg, alcohol etc., only to control our mind as the same things are diverting our health and inducing our organs towards other directions.
It is to be noted one thing in this middle. There was a practice in many houses in those days to give an enema to children as well elders periodically to keep the stomach in order. Weekly twice oil bath was taken by many people as practice. On the days of the oil bath, people avoided non-vegetarian, etc., as to avoid contradiction. Ladies used to apply turmeric powder for their faces, legs etc., and thereby they lead a life free from pimples, hair in skins etc., Nowadays people forget all such fasting, oil bath, turmeric powder etc., and running to hospitals and seeking protection from doctors.
