You eat more when the food is tasty. Then, Vaishwanara (Divinity as the digestive fire) present in your stomach starts cautioning you repeatedly, “Be careful. Be careful. Do not put anything more.” But you do not listen to this! You go on loading your stomach with tasty food items, thinking about whether you would get them again or not. Ultimately, the stomach becomes weak, and you suffer! Therefore, you should observe proper discipline in eating. If you do not follow this discipline, you will suffer from indigestion. Indigestion is the root cause of so many diseases. All diseases stem from a bad stomach. You should fill only three-quarters of your stomach (two quarters with food and one quarter with water) and leave the fourth quarter empty. If you do so, you will be following proper discipline in eating. You should follow this discipline every day. Whatever you do from dawn to dusk, perform all your activities with proper discipline. Be it worship, walking, sitting or eating, everything should be done in a disciplined way. Then your life will become exemplary. Discipline in whatever you do is verily Karma Yoga. This Karma Yoga will lead to perfection in action.
