So sāṅkhya-yoga, either you take this Kapiladeva's philosophical principle or that Kapiladeva, that's all right. But after analyzing, if you do not find out Nārāyaṇa, the creator of this material atmosphere, material elements, then it is useless laboring so much, hard, for analyzing. Just like the chemist or physicist, they are also analyzing the material elements within the laboratory. But that does not mean they are going to all be liberated at the end of life. No. Or if you want to be liberated... Because after all, you are spirit soul. You are entangled with these twenty-four elements. So your real business is how to get out of it. That is wanted. Suppose if you are a diseased fellow, or you analyze the disease. Just like in the, what is called, pathology. It is called pathology. The doctor examine your blood and he finds out, "This is infection, that is infection, this is this, this is this." That's all right. But simply by understanding the blood analysis, pathology, does not mean it is cured. The cure is different. Similarly, these sāṅkhya-yogī philosophers, they may analyze very critically. Even they can count the atoms which is composing this whole material atmosphere. But that does not mean you have understood the original force which has created all these things. That is discussed here. Etāvān sāṅkhya-yogābhyām. So you become a very big scientist, very big physicist, chemist. That is all right. But you must know how to remember Nārāyaṇa at the time of your death.
An interesting story has been described by our Satsvarūpa Mahārāja in the Back to Godhead: The learned scholar and the boatman. The boatman... In Bengal there are many rivers, and so people generally transport by boat service. So a learned scholar from Calcutta, say, was going home in the village on a boat, and he was very happy. So he was asking the boatman, "My dear boatman, do you know what are these stars, this astronomy, how they are working?" "No, sir, I do not know." "Oh, your life is twenty-five percent lost. You do not know anything." Then after some time, "You know the geology, how this earth, water, they are working?" "No, sir, I am poor man. What can I know?" "Oh, your fifty percent of your life is lost." Then all of a sudden there was a cloud, black cloud on the sky, and there was storm. Then at that time the boatman asked, "Sir, do you know how to swim?" "No, I do not know." "Then one hundred percent you have lost.(laughter) You are going to be drowned." He jumped and he drowned.
