In India, I have seen scenes of far distant places appearing as a mirage in clear air, even the colors being present to the scenes. This, though some what uncommon, was simply a remarkable instance of thought-form projection from the mind of a man highly developed along occult lines. You must remember that in order to produce a picture in the astral, of this kind, the occultist must not only have the power of will and mind to cause such a picture to materialize, but he must also have a remarkable memory for detail in the picture--for nothing appears in the picture unless it has already been pictured in the mind of the mind of the man himself. Such a memory and perception of detail is very rare--in the Western world it is possessed by only exceptional artists; however, anyone may cultivate this perception and memory if he will give the time and care to it that the Hindu magicians do. You have heard of the Hindu Mango Trick, in which the magician takes a mango seed, plants it in the ground, waves his hands over it, and then causes first a tiny shoot to appear from the surface of the ground, this followed by a tiny trunk, and leaves, which grow and grow, until at last appears a full sized mango tree, which first shows blossoms and then ripe fruit. In short, in a few moments the magician has produced that which Nature require years to do--that is he apparently does this. What he really does is to produce a wonderful thought-form in the astral, from seed stage to tree and fruit stage; the astral picture reproducing perfectly the picture in his own mind. It is as if he were creating a moving picture film-roll in his mind, and then projecting this upon the screen of the air. There is no mango tree there, and never was, outside of the mind of the magician and the minds of his audience. In the same way, the magician will seem to throw the end of a rope up into the air. It travels far up until the end is lost sight of. Then he sends a boy climbing up after it, until he too disappears from sight. Then he causes the whole thing to disappear, and lo! the boy is seen standing among the audience. The boy is real, of course, but he never left the spot--the rest was all an appearance caused by the mind and will of the magician, pictured in the astral as a thought-form. In the same way the magician will seem to cut the boy into bits, and then cause the severed parts to spring together and reassemble themselves. These feats may be varied indefinitely but the principle is ever the same--thought-form projection.
