Revelation came to the saints and saviors of humanity. It is not just a tale when we hear that the saints spoke with trees and plants in the wilderness, that a voice from the sea rose and the saints heard it, that masters talked with the sun, moon, and stars. For the deeper a person dives into life, the more he is convinced that all is living, whether beings or objects, whether art or nature; whatever he sees, whatever he perceives through the senses, whatever he can touch, all that is intelligible to him. It may not be seen and it may not be known by anybody else, but everything is communicating. Once a person begins to communicate with nature, with art, he begins to have the proof of this, for everything begins to speak. As the great poet of Persia, Sa'di, has said, "Every leaf of the tree becomes a page of the Book when once the heart is opened and it has learnt to read.'
