Each of his seven principles is derived from one of the great first seven divisions, and each relates to a planet or scene of evolution, and to a race in which that evolution was carried out. So the first sevenfold differentiation is important to be borne in mind, since it is the basis of all that follows; just as the universal evolution is septenary, so the evolution of humanity, sevenfold in its constitution, is carried on upon a septenary Earth. This is spoken of in Theosophical literature as the Sevenfold Planetary Chain, and is intimately connected with Man’s special evolution. CHAPTER III. Coming now to our Earth the view put forward by Theosophy regarding its genesis, its evolution and the evolution of the Human, Animal and other Monads, is quite different from modern ideas, and in some things contrary to accepted theories. But the theories of to-day are not stable. They change with each century, while the Theosophical one never alters because, in the opinion of those Elder Brothers who have caused its repromulgation and pointed to its confirmation in ancient books, it is but a statement of facts in nature. The modern theory is, on the contrary, always speculative, changeable, and continually altered. Following the general plan outlined in preceding pages, the Earth is sevenfold. It is an entity and not a mere lump of gross matter. And being thus an entity of a septenary nature there must be six other globes which roll with it in space. This company of seven globes has been called the “Earth Chain”, the “Planetary Chain”. In _Esoteric Buddhism_ this is clearly stated, but there a rather hard and fast materialistic view of it is given and the reader led to believe that the doctrine speaks of seven distinct globes, all separated from though connected with each other. One is forced to conclude that the author meant to say that the globe Earth is as distinct from the other six as Venus is from Mars.
