In this world matter and force are widely different. The chief characteristic of matter here is _inertia_: the tendency to remain at rest until acted upon by a force which sets it in motion. In the Desire World, on the contrary, force and matter are almost indistinguishable one from the other. We might almost describe desire-stuff as force-matter, for it is in incessant motion, responsive to the slightest _feeling_ of a vast multitude of beings which populate this wonderful world in nature. We often speak of the “teeming millions” of China and India, even of our vast cities, London, New York, Paris or Chicago, we consider them overcrowded in the extreme, yet even the densest population of any spot upon earth is sparsely inhabited compared with the crowded conditions of the Desire World. No inconvenience is felt by any of the denizens of that realm, however, for, while in this world two things cannot occupy the same space at the same time, it is different there. A number of people and things may exist _in the same place at the same time_ and be engaged in most diverse activities, regardless of what others are doing, such is the wonderful elasticity of desire stuff. As an illustration we may mention a case where the writer while attending religious service, plainly perceived at the altar certain beings interested in furthering that service and working to achieve that end. At the same time there drifted through the room and the altar, a table at which four persons were engaged in playing cards. They were as oblivious to the existence of the beings engaged in furthering our religious service, as though these did not exist. The Desire World is the abode of those who have died, for some time subsequent to that event, and we may mention in the above connection that the so-called “dead” very often stay for a long while among their still living friends. Unseen by their relatives they go about the familiar rooms. At first they are often unaware of the condition mentioned: “that two persons may be in the same place at the same time,” and when they seat themselves in a chair or at the table, a living relative may take the supposedly vacant seat. The man we mistakenly call dead will at first hurry out of his seat to escape being sat upon, but he soon learns that being sat upon does not hurt him in his altered condition, and that he may remain in his chair regardless of the fact that his living relative is also sitting there. In the lower regions of the Desire World the whole body of each being may be seen, but in the highest regions only the head seems to remain. Raphael, who like many other people in the middle ages was gifted with a so-called _second sight_, pictured that condition for us in his Sistine Madonna, now in the Dresden Art Gallery, where Madonna and the Christ-child are represented as floating in a golden atmosphere and surrounded by a host of genie-heads: conditions which the occult investigator knows to be in harmony with actual facts.
