An elemental is a center of force, without intelligence, as we understand the word, without moral character or tendencies similar to ours, but capable of being directed in its movements by human thoughts, which may, consciously or not, give it any form, and endow it to a certain extent with what we call intelligence. We give them form by a species of thought which the mind does not register--involuntary and unconscious thought--"as, one person might shape an elemental so as to seem like an insect, and not be able to tell whether he had thought of such a thing or not." The elemental world interpenetrates this one, and elementals are constantly being attracted to, or repelled from, human beings, taking the prevailing color of their thoughts. Time and space, as we understand them, do not exist for elementals. They can be seen clairvoyantly in the shapes they assume under different influences, and they do many of the phenomena of the seance room. Light and the concentrated attention of any one make a disturbance in the magnetism of a room, interfering with their work in that respect. At seances elementaries also are present; these are shells, or half-dead human beings. The elementaries are not all bad, however, but the worst are the strongest, because the most attracted to material life. They are all helped and galvanized into action by elementals. Contact with these beings has a deteriorating effect in all cases. Clairvoyants see in the astral light surrounding a person the images of people or events that have made an impression on that person's mind, and they frequently mistake these echoes and reflections for astral realities; only the trained seer can distinguish. The whole astral world is full of illusions. Elementals have not got _being_ such as mortals have. There are different classes for the different planes of nature. Each class is confined to its own plane, and many can never be recognized by men. The elemental world is a strong factor in Karma. Formerly, when men were less selfish and more spiritual, the elementals were friendly. They have become unfriendly by reason of man's indifference to, and want of sympathy with the rest of creation. Man has also colored the astral world with his own selfish and brutal thoughts, and produced an atmosphere of evil which he himself breathes. When men shall cultivate feelings of brotherly affection for each other, and of sympathy with nature, the elementals will change their present hostile attitude for one of helpfulness. Elementals aid in the performance of phenomena produced by adepts. They also enter the sphere of unprotected persons, and especially of those who study occultism, thus precipitating the results of past Karma.
