Thus our evolution is going forward and has gone forward in the past. We know that the human race has passed through a long evolution during which it has acquired five senses by which knowledge is gained. Nobody who has given thought to the subject will make the mistake of supposing that this evolution is completed and that the five senses are all we shall ever possess. In this long evolutionary journey the next thing we shall do is to develop the sixth sense. Some people have already done so and all are approaching it. This dawning sense is called clairvoyance. Fair investigation will show that the clairvoyant possesses certain powers not common to the majority of people. This is merely the beginning of the development of the sixth sense, and probably with the majority of clairvoyants it goes no further than etheric and lower astral sight. In other words, they are able to raise the consciousness only to a grade of matter a little beyond the grasp of ordinary vision, while the properly developed, trained clairvoyant raises his consciousness two full planes beyond. The higher the consciousness is raised the further the horizon of knowledge extends and the clairvoyant is able to hand down information that appears quite miraculous; but it is perfectly natural. If a certain person were born blind and had never understood any more about eyesight than most people understand about clairvoyance; if this person could know how many doorways were in a large building only by groping along with his hands and thus acquiring the knowledge by touch, and another person who could see should glance along the block and instantly tell the blind man the correct number, that would be to the blind man a miracle. Now, when a clairvoyant sees things at a distance where the physical eye cannot reach he really does nothing more remarkable. When we see a thing we receive the vibrations caused by light. That gives the information. When the clairvoyant "sees" at a distance through what we mistakenly call solid substances he receives vibrations of matter so fine that it interpenetrates solids as the ether does. Every human being must make, and is making, this long evolutionary journey from spiritual infancy to godlike power and perfection, but there are two ways in which it may be done. We may, as the vast majority do, accept the process of unconscious evolution and submit to nature's whip and spur that continuously urge the thoughtless and indifferent forward until they finally reach the goal. Or, we may choose conscious evolution and work intelligently with nature, thus making progress that is comparatively of enormous rapidity and at the same time avoid much of what Hamlet called the "slings and arrows of outrageous fortune."
