The sub‐races are also subject to the same cleansing process, and the side‐branchlets or family‐races as well. Let any one, well acquainted with astronomy and mathematics, throw a retrospective glance into the twilight and shadows of the Past. Let him observe and take notes of what he knows of the history of peoples and nations, and collate their respective rises and falls with what is known of astronomical cycles—especially with the Sidereal Year, which is equal to 25,868 of our solar years.(737) Then, if the observer is gifted with the faintest intuition, he will find how the weal and woe of nations are intimately connected with the beginning and close of this Sidereal Cycle. True, the non‐occultist has the disadvantage that he has no such far distant times to rely upon. He knows nothing, through exact Science, of what took place nearly 10,000 years ago; yet he may find consolation in the knowledge of, or—if he so prefers—speculation about, the fate of every one of the modern nations he knows of—some 16,000 years hence. Our meaning is very clear. Every Sidereal Year the tropics recede from the pole _four degrees_ in each revolution from the equinoctial points, as the equator turns through the Zodiacal constellations. Now, as every Astronomer knows, at present the tropic is only twenty‐three degrees and a fraction less than half a degree from the equator. Hence it has still two and a half degrees to run before the end of the Sidereal Year. This gives humanity in general, and our civilized races in particular, a reprieve of about 16,000 years. After the Great Flood of the Third Race (the Lemurians) as Commentary Thirty‐three tells us: _Men decreased considerably in stature, and the duration of their lives was diminished. Having fallen down in godliness they mixed with animal races, and intermarried among giants and pigmies [the dwarfed races of the Poles].... Many acquired divine, nay more—unlawful knowledge, and followed willingly the Left Path._ Thus were the Atlanteans approaching destruction in their turn. How many geological periods it took to accomplish this _fourth_ destruction who can tell! But we are told that: 44. THEY(738) BUILT GREAT IMAGES NINE YATIS HIGH,(739) THE SIZE OF THEIR BODIES (_a_). INNER FIRES HAD DESTROYED THE LAND OF THEIR FATHERS.(740) WATER THREATENED THE FOURTH(741) (_b_).
