The process of contemplation is like the work of the camera: when the camera is put before a certain object and has been properly focused, then only that object is received by the camera. And therefore when an object before one is limited, then one can see that object more clearly. What constitutes the appeal of the poet is that he tells his readers of something he has seen behind these generally recognized ideas. The prophet goes still further. He not only contemplates one idea, but he can contemplate on any idea. There comes a time in the life of the prophet or of anyone who contemplates, when whatever object he casts his glance upon opens up and reveals to him what it has in its heart. In the history of the world we see that besides their great imagination, their great dreams, their ecstasy and their joy in the divine life, the prophets have often been great reformers, scientists, medical men or even statesmen.
