Prabhupada, Philadelphia, July 14, 1975: People are making research work about the bodily cells, how they are working, and so many things, simply on the body. But as soon as you become cleansed of your heart, then immediately you understand, “I am not this body, so what is the use of studying the cells and atoms and this and that? I am not this body.” Immediately. “Actually, I am not this body. I am simply wasting my time in studying.” The same thing, example, that I am in the car, I am studying the machine only. I forgot my destination, where I have to go. I am busy with studying the car. What is the use? You must know. You have got a good car. You must know where is the destination, where you have to go. That is your business. The business… Of course, it is secondary. If you want to know what is the car, that is secondary; that is not your main business. The main business is how to utilize the car and go to my destination. That is intelligence.
So we are fallen in this material condition in different forms. So long we are in this bodily concept, “I am this car,” that is ignorance. I am not this car, but I have to utilize this car for going to my destination. That is wanted. So I am not this body. I am spirit soul. My destination is how to go to the spiritual world, how to meet the supreme spirit, God, and live with Him in His association. So this life is meant for understanding what is the Supreme Lord, where does He live, what does He do, what is my relationship with Him. This is called brahma-jijnasa. That is actual education. And I am given this machine. If we simply study the machine, then what is the use of it? The sastra says that machine is working, and it will work until it is rotten. So you don’t bother with the machine, but you simply appreciate that you have got now a good machine. The dog has got also a machine, and a human being has got a machine. Everyone has got a machine, living entity, but the sastra says, “This machine should not be utilized like the dog’s machine.” Nayam deho deha-bhajam nri loke… Everyone has got machine. Even an ant, it has got machine, because according to his desire, he has been given a body. That is also machine. An elephant has got a machine. I am also. I have got also machine. Every one of us, we are spirit soul, and relatively we have got different machine. So that machine is required for going from here. But we should not waste our time simply studying the machine, forgetting our destination. This is human intelligence. God has already given you a type of machine. Now utilize it to go to the destination.
Nr-deham adyam sulabham sukalpam. This nr-deham, this machine is very carefully made not by me, but by the nature. Nature is the agent of God. I wanted to do something. That means I require a particular type of machine. God orders nature that “This living entity wants something like this. You give him a machine.” So the prakrti, or the nature, gives us different types of machine. Prakrteh kriyamanani gunaih karmani sarvasah [Bg. 3.27]. I am neither driving the machine; neither I have made the machine. I have been given as gift to work on or to fulfill my desire. This is the position. So sastra says that “You have got now a very good machine.” Nr-deham. The human form of body is very good machine. Nr-deham adyam sulabham sukalpam. It is very rare. With great difficulty, you have got this machine because we have to come through so many machines, the aquatics, the plants, the insects, the trees, and the serpents, reptiles, then birds, then beast, millions and millions of years. Just like you have seen this. The trees are standing there, maybe standing for five thousand years. So if you get that machine, you cannot move. You have to stand in one place. So we had to go through this. Foolish people, they do not know.
Therefore this machine is sulabham. Sulabham means very fortunately we have got this machine. And sukalpam, “very nicely made.” Those who are medical man, they see how nicely made it is, how the nerves are working, the nails are working, the intestines and the heart and everything—a grand machine. Therefore it is called sukalpam, “very well planned.” And what for? Just like a nice boat, well planned. If you have got a nice boat, you get on it and cross over the river or the ocean. Similarly, we are in this material ocean. Life after life we are struggling. So now we have got a nice boat, this human body. Sulabham sudurlabham.
