“Arjuna! Sāttvika food must be such as gives strength to the mind and to the body. It must not have too much salt, too much chilli, too much sourness, too much sweetness or too much heat. Not only that, it must not be the kind that causes thirst either. It must be moderate in every respect. Some people eat things cooked in water on the second day; that is to say, even rice cooked the day before must not be eaten.”
