There are certain psychic conditions which are especially conducive to the manifestation of clairvoyant phenomena, as all students of the subject know very well. These conditions are somewhat hard to induce, at least until the clairvoyant has had considerable experience and practice. But, in the state of sleep, the person induces the desired conditions, in many cases, though he is not consciously doing so. As might naturally be expected, therefore, the majority of the recorded cases of clairvoyance have occurred when the clairvoyant person has been asleep.
I should also state, once more, that in many cases in which the clairvoyant has witnessed the “appearance” of another person, as in the cases such as I have just mentioned, there is always the possibility of the person having actually appeared in his astral body, unconsciously to himself of course. No one but a skilled occultist is able to distinguish between cases of this kind. The line between this class of clairvoyance and astral appearance is very thin, and, in fact, the two classes of phenomena shade and blend into each other. In reality, when one gets down to bottom principles, there is very little difference between the actual appearance in the astral body, and the strong projection of one’s presence by means of will, conscious or unconscious, along the lines of awakening the clairvoyant vision of others. To attempt to explain the slight points of difference here, would only involve the student in a mass of technical description which would tend to confuse, rather than to enlighten him—from this I refrain.
CLAIRVOYANCE OF THE PAST
The third great class of clairvoyant phenomena, known as Time Clairvoyance, is divided into two sub-classes, as follows: (1) Past-Time Clairvoyance; and (2) Future-Time Clairvoyance. The characteristics of each of these sub-classes is indicated by its name.
Past-Time Clairvoyance, as indicated by the name, is that class of clairvoyant phenomena which is concerned with the perception of facts, events and happenings of past time. Whether the happening is that of five minutes ago, or of five thousand years ago, the principles involved are precisely the same. One is no more or less wonderful than is the other.
