When he first attains to this clear vision, he sees not only that which brings him great joy but also that which brings him great sorrow. He sees men bewildered by life, pained by life, blinded by life. He sees them wandering into wrong paths because there is no one to lead them into right ones. He sees them praying for light but surrounded by darkness. In that hour he makes a decision which will fundamentally affect the whole of his life. Henceforth he will intercede for these others, devote himself to their spiritual service.
