The modern education, they are simply giving lessons on some art, generally known as technology. So by that advancement of knowledge we can construct high skyscraper building, nice motorcar, nice airplane, nice machine. That is art. But we do not know what is going to happen next life, my soul. That we do not.
So this is the distinction between avidyā and vidyā. Vidyā means knowledge, and avidyā means ignorance. Suppose you construct a very nice skyscraper building and next life you become something—you remain a rat in that house—then what is your benefit? The soul has to accept a body according to his karma. If by karma he has to accept the body of a rat, it will not be excused by nature that "You have constructed skyscraper building; therefore you'll again come and live there." No, that is not possible. If by karma you are fit for becoming a rat or cat, nature will give you that body.
