“... _It is quite correct that Mars is in a state of obscuration at present, and Mercury just beginning to get out of it. You might add that Venus is in her last Round.... If neither Mercury nor Venus have satellites, it is because of the reasons ... and also because Mars has two satellites to which he has no right.... Phobos, the supposed __‘__inner__’__ satellite, is no satellite at all. Thus, this remark of long ago by Laplace and now by Faye do not agree, you see. (Read __‘__Comptes Rendus,__’__ __ Tome XC, p. 569.)

Remember:_ _... knowledge dwells_ _In heads replete with thoughts of other men,_ _Wisdom in minds attentive to their own_....” “_You can never impress it too profoundly on the minds of those to whom you impart some of the Esoteric teachings_.” Here are more extracts from another letter written by the same authority. This time it is in answer to some objections laid before the Teachers. They are based upon extremely scientific, and as futile, reasonings about the advisability of trying to reconcile the Esoteric theories with the speculations of Modern Science, were written by a young Theosophist as a warning against the “Secret Doctrine,” and in reference to the same subject. He had declared that if there were such companion Earths, “they must be only a wee bit less material than our globe.” How then was it that they could not be seen? The answer was:
