The Moon chain with the Earth chain formed two units, or two polarities, negative and positive. The point of merging was reached, and the Earth chain absorbed or synthesized the moon chain in the same sense as certain of the schemes will merge until only three will apparently be left. Therefore the Earth chain is essentially dual in its nature, being the sumtotal of a male and a female chain. This is a mystery impossible to elucidate further, but it is dealt with in certain occult books, and hinted at by H. P. B. (S. D., I, Section IX, Vol. I, 176-200)

In due course of time another merging in the scheme will eventuate and then Uranus (the chain of that name in our scheme) will flash into objectivity. Forget not that the schemes manifest as seven, as ten, as three from the angle of the Eternal Now, or - from the point of view of a Heavenly Man - the manifestation may be written as . In time and space the order might be stated to be 7-3-10, and at certain stages 10-7-3. As [415] the opposites merge the ten become the seven and the three, and it is during this process that entire chains and globes, and eventually schemes, will apparently vanish from objectivity, and drop out of sight. They will be simply absorbed. During the twofold process of evolution, it might be numerically expressed as:

• During involution the sequence is seen as three, then seven and finally ten.
• During evolution the sequence is ten, then seven and finally three.

The Moon chain has in itself a curious occult history, not yet to be disclosed. This differentiates it from the other chains in the scheme and even from any other chain in any scheme. An analogous situation or correspondence will be found in another planetary scheme within the solar system. All this is hidden in the history of one of the solar systems which is united to ours within a cosmic ring-pass-not. Hence the impossibility of yet enlarging upon it. Each Heavenly Man of a scheme is a focal point for the force and power and vibratory life of seven stupendous ENTITIES in exactly the same sense [416] as the seven centers in a human being are the focal points for the influence of a corresponding heavenly Prototype. Our Heavenly Man, therefore, is esoterically allied to one of the seven solar systems, and in this mysterious alliance is hidden the mystery of the moon chain.

• The Moon chain was a chain wherein a systemic failure was to be seen.
• It is connected with the lower principles, which H.P.B. has stated are now superseded.
• The sexual misery of this planet finds its origin in the moon failure.
• The progress of evolution on the moon was abruptly disturbed and arrested by the timely interference of the solar Logos. The secret of the suffering in the Earth chain, which makes it merit the name of the Sphere of Suffering, and the mystery of the long and painful watch kept by the SILENT WATCHER, ⁴⁸ has its origin in the events which brought the moon chain to a terrific culmination. Conditions of agony and of distress such as are found on our planet are found in no such degree in any other scheme. [417]
• The misuse of the vibratory power of a certain center, and the perversion, or distortion of force to certain erroneous ends, not along the line of evolution, account for much of the moon mystery.
• Certain results, such as the finding of its polar opposite, were hastened unduly on the moon chain, and the consequence was an uneven development and a retardation of the evolution of a certain number of deva and human groups.
• The origin of the feud between the Lords of the Dark Face and the Brotherhood of Light, which found scope for activity in Atlantean days, and during the present root race, can be traced back to the moon chain.

48 ...it is He, again, who holds spiritual sway over the initiated Adepts throughout the whole world. He is, as said, the "Nameless One" who has so many names, and yet whose names and whose very nature are unknown. He is the 'Initiator,' called the 'Great Sacrifice.' For, sitting at the Threshold of Light, he looks into it from within the Circle of Darkness, which he will not cross; nor will he quit his post till the last Day of this Life-Cycle. Why does the Solitary Watcher remain at his self-chosen post? Why does he sit by the Fountain of Primeval Wisdom, of which he drinks no longer, for he has naught to learn which he does not know - aye, neither on this Earth, nor in its Heaven? Because the lonely, sorefooted Pilgrims, on their journey back to their Home, are never sure, to the last moment, of not losing their way, in this limitless desert of Illusion and Matter called Earth-Life. Because he would fain show the way to that region of freedom and light, from which he is a voluntary exile himself, to every prisoner who has succeeded in liberating himself from the bonds of flesh and illusion. Because, in short, he has sacrificed himself for the sake of Mankind, though but a few elect may profit by the Great Sacrifice." - S. D., I, 229.
