The Yogi as well as the Philosopher revolts against this bondage of the human mind. Both of them aspire to break through the walls of this prison. They want to transcend the limitations, under which the ordinary human consciousness is placed by nature. For the satisfaction of the innermost craving of their souls, they attempt to penetrate into the innermost meaning of this cosmic order. However bewilderingly complex the constitution of the world of our normal experience may appear to be, it cannot be a meaningless and purposeless process, going on by chance or accident. The wonderful order and harmony perceptible in all the departments of this complicated system of the Universe point to some dynamic center or Soul of this system, some obviously inscrutable Governing Principle or Power regulating its intricate operations, some Supreme Ideal which is being realized in and through this continuous phenomenal process. A Yogi and a Philosopher are both inspired by some such faith, and both of them devote their energy to the discovery of that center or Soul of the Universe, that Governing Principle or Power, that Supreme Ideal, which may furnish a rational explanation of this world-order and give a meaning to it.
