8.7 On drinking water, Chanakya says that the stomach is an important organ. It is the stomach which controls your fitness. It is, therefore, essential that a man should keep his digestion in order. In case of indigestion, water acts as a medicine. So, drink a lot of water, but do so before taking food or after digestion of the food. If water is taken immediately after taking food, it acts like slow poison and deteriorates the body.
