Just like this finger is part and parcel of my body. Its business is to serve the body. That is the business. There is no other business. A finger can pick up a rasagulla and keep it here. The finger cannot eat. Similarly, we cannot eat directly. That is our diseased condition. We have to offer Krsna. When Krsna eats, if we eat that, then we become energized. Just like you rasagulla put into the mouth. When it goes to the stomach, the finger immediately becomes reddish. The finger enjoys. Not only the finger, the eyes enjoy, the legs enjoy, because the energy is distributed. Directly we cannot be energized by eating. We must eat Krsna's prasadam. This is principle. Jivera svarupa haya nitya krsna dasa [Cc. Madhya 20.108-109].
