Food must be consumed with a purpose behind each bite. You must eat food that is nourising and ensure the nourishment DOES NOT go to waste in idling. Consumption must not be accompanies by anything to distract the mind, to make it idle for otherwise you lose sight of the purpose of this food — what dreams it shall allow you to fulfill, to allow you to move, to think, to act; to create.
Food, mind and purpose, all together in isolation.
