Intuition need not be the only manifestation of this deeper layer of mind. There are indeed other and stranger signs of its existence, which belong to a classification variously called occult, magical, or psychic. They include thought-transference and clairvoyance. The history of yoga has always been associated with stories of such thaumaturgic marvels, and few advanced yogis fail to manifest these powers at some period or other of their careers.
Such are some of the extraordinary mental powers which may be unfolded by man, but they are of secondary consequence to the sage. He holds to and values most the remaining constantly fixed within that universal being which transcends all forms and changes.
Nevertheless the average scientist who used to sneer at their existence has since become much more cautious, although a remnant of materialistic scientists still continue to sneer. Such people represent a type of mind which dreads superstition to the point of making its dread a superstition! These supernormal powers of the mind lose much of their mystery when their rationale is understood.
When the entire world itself is mentally constructed--that is, a kind of magical show--why should we be incredulous of the possibility of magical powers? All of us have these powers in vestigial form. Evolution will make them grow anyway, and effort will make them grow more quickly. However surprising to beginners, they are realizable facts to an adept.
Telepathy is perhaps the first, simplest, and most easily explicable of these powers.
