"The rapport with this realm of beings is generally due to certain proclivities in the individual; or, when whole communities are affected, the cause proceeds from revolutionary movements in the realms of astral fluid; these continually affect the elementals, who, in combination with low undeveloped spirits of humanity (elementaries), avail themselves of magnetic epidemics to obsess susceptible individuals, and sympathetically affect communities."

In the introduction to Isis Unveiled, we find the following definition of elementary spirits:

"Properly, the disembodied souls of the depraved; these souls, having at some time prior to death, separated from themselves their divine spirits, and so lost their chance of immortality. Eliphas Lévi and some other Kabalists make little distinction between elementary spirits, who have been men, and those beings which people the elements and are the blind forces of nature. Once divorced from their bodies, these souls (also called astral bodies) of purely materialistic persons, are irresistibly attracted to the earth, where they live a temporary and finite life amid elements congenial to their gross natures. From having never, during their natural lives, cultivated this spirituality, but subordinated it to the material and gross, they are now unfitted for the lofty career of the pure, disembodied being, for whom the atmosphere of earth is stifling and mephitic, and whose attractions are all away from it. After a more or less prolonged period of time these material souls will begin to disintegrate, and finally, like a column of mist, be dissolved, atom by atom, in the surrounding elements.—(Preface xxx., vol. I.)

"After the death of the depraved and the wicked, arrives the critical moment. If during life the ultimate and desperate effort of the inner-self to reunite itself with the faintly-glimmering ray of its divine parent is neglected; if this ray is allowed to be more and more shut out by the thickening crust of matter, the soul, once freed from the body, follows its earthly attractions, and is magnetically drawn into and held within the dense fogs of the material atmosphere. Then it begins to sink lower and lower, until it finds itself, when returned to consciousness, in what the ancients termed Hades. The annihilation of such a soul is never instantaneous; it may last centuries perhaps; for nature never proceeds by jumps and starts, and the astral soul, being formed of elements, the law of evolution must bide its time. Then begins the fearful law of compensation, the Yin-Youan of the Buddhists. This class of spirits is called the terrestrial, or earthly elementary, in contradistinction to the other classes." (They frequent séance rooms, &c.)—(P. 319, vol. I.)

Of the danger of meddling in occult matters before understanding the elementals and elementaries, Isis says, in the case of a rash intruder:

"The spirit of harmony and union will depart from the elements, disturbed by the imprudent hand; and the currents of blind forces will become immediately infested by numberless creatures of matter and instinct—the bad demons of the theurgists, the devils of theology; the gnomes, salamanders, sylphs, and undines will assail the rash performer under multifarious aerial forms. Unable to invent anything, they will search your memory to its very depths; hence the nervous exhaustion and mental oppression of certain sensitive natures at spiritual circles. The elementals will bring to light long-forgotten remembrances of the past; forms, images, sweet mementos, and familiar sentences, long since faded from our own remembrance, but vividly preserved in the inscrutable depths of our memory and on the astral tablets of the imperishable 'Book of Life.'"—(P. 343, vol. I.)

Paracelsus speaks of Xeni Nephidei: "Elemental spirits that give men occult powers over visible matter, and then feed on their brains, often causing thereby insanity.

"Man rules potentially over all lower existences than himself," says the author of Art Magic (p. 333), "but woe to him, who by seeking aid, counsel, or assistance, from lower grades of being, binds himself to them; henceforth he may rest assured they will become his parasites and associates, and as their instincts—like those of the animal kingdom—are strong in the particular direction of their nature, they are powerful to disturb, annoy, prompt to evil, and avail themselves of the contact induced by man's invitation to drag him down to their own level. The legendary idea of evil compacts between man and the 'Adversary' is not wholly mythical. Every wrong-doer signs that compact with spirits who have sympathy with his evil actions.

"Except for the purposes of scientific investigation, or with a view to strengthening ourselves against the silent and mysterious promptings to evil that beset us on every side, we warn mere curiosity-seekers, or persons ambitious to attach the legions of an unknown world to their service, against any attempts to seek communion with elemental spirits, or beings of any grade lower than man. Beings below mortality can grant nothing that mortality ought to ask. They can only serve man in some embryonic department of nature, and man must stoop to their state before they can thus reach him.... Knowledge is only good for us when we can apply it judiciously. Those who investigate for the sake of science, or with a view to enlarging the narrow boundaries of man's egotistical opinions, may venture much further into the realms of the unknown than curiosity-seekers, or persons who desire to apply the secrets of being to selfish purposes. It may be as well also for man to remember that he and his planet are not the all of being, and that, besides the revelations included in the stupendous outpouring called 'Modern Spiritualism,' there are many problems yet to be solved in human life and planetary existences, which spiritualism does not cover, nor ignorance and prejudice dream of.... Besides these considerations, we would warn man of the many subtle, though invisible, enemies which surround him, and, rather by the instinct of their embryonic natures than through malice prepense, seek to lay siege to the garrison of the human heart. We would advise him, moreover, that into that sacred entrenchment no power can enter, save by invitation of the soul itself. Angels may solicit, or demons may tempt, but none can compel the spirit within to action, unless it first surrenders the will to the investing power."—(Art Magic, p. 335.)

From the Theosophist of July 1886, we make the following extract, bearing upon the subject of the loss of immortality by soul-death, and the dangers of Black Magic:
