The first point which it is necessary to make clear in describing the astral plane is its absolute reality. Of course in using that word I am not speaking from that metaphysical standpoint from which all but the One Unmanifested is unreal because impermanent; I am using the word in its plain, every-day sense, and I mean by it that the objects and inhabitants of the astral plane are real in exactly the same way as our own bodies, our furniture, our houses or monuments are real - as real as Charing Cross, to quote an expressive remark from one of the earliest Theosophical works. They will no more endure for ever than will objects on the physical plane, but they are nevertheless realities from our point of view while they last - realities which we cannot afford to ignore merely because the majority of mankind is as yet unconscious, or but vaguely conscious, of their existence.
