"Eat only what you need to eat. Do not be greedy. Do not take more than you can eat and waste the rest, because wasting food is a great sin. The surplus food can feed another stomach. Do not waste food, because food is God, life is God, and man is born from food. Food is the main source of man's life, body, mind and character."

"The gross part of the food, which is the major portion of the food consumed by the body, 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 the mind. Therefore, the mind is the reflection of the food consumed. The reason for the present beastly and demonic tendencies in our minds is the food we consume."

"Offer service to someone in need, with a full heart and experience the ananda that results. It need not be something big; it can even be small and unnoticed by others. It has to be done to please the God within you and him."
