And, now let us pass on to a consideration of the various forms and phases of the clairvoyant phenomena itself. The subject is fascinating, and I am sure that you will enjoy this little excursion into the strange realm of thought regarding the astral phenomena of clairvoyance. But, be sure to master each lesson before proceeding to the rest, as otherwise you will have to turn back the leaves of the course in order to pick up some point of teaching that you have neglected. LESSON IX. SIMPLE CLAIRVOYANCE. In a previous chapter we have seen that there are three well-defined classes of clairvoyance, namely, (1) Simple clairvoyance; (2) Clairvoyance in space; and (3) Clairvoyance in Time. I shall now consider these in sequence, beginning with the first, Simple Clairvoyance. In simple clairvoyance the clairvoyant person merely senses the auric emanations of other persons, such as the auric vibrations, colors, etc., currents of thought vibrations, etc., but does not see events or scenes removed in space or time from the observer. There are other phenomena peculiar to this class of clairvoyance which I shall note as we progress with this chapter. An authority on the subject of astral phenomena has written interestingly, as follows, regarding some of the phases of simple clairvoyance: "When we come to consider the additional facilities which it offers in the observation of animate objects, we see still more clearly the advantages of astral vision. It exhibits to the clairvoyant the aura of plants and animals, and thus in the case of the latter their desires and emotions, and whatever thoughts they may have, are all plainly shown before his eyes. But it is in dealing with human beings that he will most appreciate the value of this faculty, for he will often be able to help them far more effectually when he guides himself by the information which it gives him. "He will be able to see the aura as far up as the astral body, and though that leaves all the higher part of a man still hidden from his gaze, he will nevertheless find it possible by careful observation to learn a good deal about the higher part from what is within his reach. His capacity of examination of the etheric double will give him considerable advantage in locating and classifying any defects or diseases of the nervous system, while from the appearance of the astral body he will at once be aware of all the emotions, passions, desires and tendencies of the man before him, and even of very many of his thoughts also.
