Food is considered God, as it is the source of a person’s life, body, mind, and character. Eat only what you need. Do not be greedy and take more than you can eat and waste the rest. Wasting food is a great sin; your surplus can feed another stomach. Even a major part of the food you consume, the gross part, is thrown out as waste matter. A minute amount of the food, which is the subtle part, is assimilated by the body and flows as blood. And a minuscule amount, which is the subtlest part of the food, makes up your mind. Therefore mind is the reflection of the food consumed. When demonic tendencies arise in our minds, know that it is from the food we consume. To receive real nourishment, pay attention to the quality of food that you eat and let it be very pure, clean, sanctified, and Satwik.
