The Astral Form clothing the Monad was surrounded, as it still is, by its egg‐shaped sphere of Aura, which here corresponds to the substance of the germ‐cell or Ovum. The Astral Form itself is the nucleus, now, as then, instinct with the Principle of Life. When the season of reproduction arrives, the _Sub_‐astral “extrudes” a miniature of itself from the egg of surrounding Aura. This germ grows and feeds on the Aura till it becomes fully developed, when it gradually separates from its parent, carrying with it its own sphere of Aura; just as we see living cells reproducing their like by growth and subsequent division into two. The analogy with the “polar cells” would seem to hold good, since their death would _now_ correspond to the change introduced by the separation of the sexes, when gestation _in utero_, _i.e._, within the cell, became the rule. As the Commentary tells us: _The early Second [Root] Race were the Fathers of the __“__Sweat‐ born__”__; the later Second [Root] Race were __“__Sweat‐born__”__ themselves._ This passage from the Commentary refers to the work of evolution from the beginning of a Race to its close. The “Sons of Yoga,” or the Primitive Astral Race, had seven stages of evolution _racially_, or collectively; as every individual Being in it had, and has now. It is not Shakespeare only who divided the ages of man into a series of seven, but Nature herself. Thus the first Sub‐races of the Second Race were born at first by the process described on the law of analogy; while the last began gradually, _pari passu_ with the evolution of the human body, to be formed otherwise. The process of reproduction had seven stages also in each Race, each covering æons of time. What Physiologist or Biologist can tell whether the present mode of generation, with all its phases of gestation, is older than half a million, or at most one million of years, since their cycle of observation began hardly half a century ago? Primeval human Hermaphrodites are a fact in Nature well known to the Ancients, and form one of Darwin’s greatest perplexities. Yet there is certainly no impossibility, but, on the contrary, a great probability that hermaphroditism existed in the evolution of the early Races; while on the grounds of analogy, and on that of the existence of one universal law in physical evolution, acting indifferently in the construction of plant, animal, and man, it must be so. The mistaken theories of Monogenesis, and the descent of man from the mammal, instead of the mammals from man, are fatal to the completeness of evolution as taught in modern schools on Darwinian lines, and they will have to be abandoned in view of the insuperable difficulties which they encounter. Occult tradition—if the terms Science and Knowledge are denied in this particular to Antiquity—can alone reconcile the inconsistencies and fill the gap. Says a Talmudic axiom: If thou wilt know the invisible, open thine eyes wide on the visible.
