Details – Everything is the effect of food. Eaten food turns into "brandy" (that which produces a deleterious effect on a person's awareness)in the body. These effects are directly linked with spiritual awareness. Heavy or excessive food decreases spiritual and mental awareness. Non-vegetarian food is heavy and does not allow the development of one's spiritual intellect. If you want to progress spiritually you must eat vegetarian food, which is light and does not create intoxication. It also helps in increasing awareness.
