Among the manipulating devas of the lowest level of the dense physical plane are to be found certain subterranean forms of existence, of which hints are to be found in the ancient and occult books.
There is to be found in the very bowels of the earth, an evolution of a peculiar nature, with a close resemblance to the human. They have bodies of a peculiarly gross kind, which might be regarded as distinctly physical as we understand the term. They dwell in settlements, or groups, under a form of government suited to their needs in the central caves several miles below the crust of the earth. Their work is closely connected with the mineral kingdom, and the "agnichaitans" of the central fires are under their control. Their bodies are constituted so as to stand much pressure, and they are not dependent upon as free a circulation of air as man is, nor do they resent the great heat to be found in the earth's interior. Little can here be communicated anent these existences, for they are connected with the lesser vital portions of the physical body of the planetary Logos, finding their microcosmic correspondence in the feet and legs of a man. They are one of the factors which make possible the revolutionary progressive activity of a planet.
Allied with them are several other groups of low class entities, whose place in the scheme of things can only be described as having relation to the grosser planetary functions. Little is gained by enlarging upon these lives and their work; it is not possible for man in any way to contact them, nor would it be desirable. When they have pursued their evolutionary cycle, they will take their place in a later cycle in the ranks of certain deva bodies that are related to the animal kingdom.
It is commonly supposed that all the fairies, gnomes, elves, and like nature spirits are to be found solely in etheric matter, but this is not so. They are to be found in bodies of gaseous and liquid substance likewise, but the mistake has arisen for the reason that the basis of all that which can be objectively seen is the etheric structure, and these little busy lives frequently protect their dense physical activities through the agency of glamor, and cast a veil over their objective manifestation. When etheric vision is present then they can be seen, for the glamor, as we understand it, is only a veil over that which is tangible. (Treatise On Cosmic Fire)
