It thus becomes patent why we could not perceive, even with the help of the best telescopes, that which is outside our world of matter. Those alone, whom we call Adepts, who know how to direct their mental vision and to transfer their consciousness—both physical and psychic—to other planes of being, are able to speak with authority on such subjects. And they tell us plainly:

“_Lead the life necessary for the acquisition of such knowledge and powers, and Wisdom will come to you naturally. Whenever you are able to attune your consciousness to any of the seven chords of __‘__Universal Consciousness,__’__ those chords that run along the sounding‐board of Kosmos, vibrating from one Eternity to another; when you have studied thoroughly the __‘__Music of the Spheres,__’__ then only will you become quite free to share your knowledge with those with whom it is safe to do so. Meanwhile, be prudent. Do not give out the great Truths that are the inheritance of the future Races, to our present generation. Do not attempt to unveil the secret of Being and Non‐Being to those unable to see the hidden meaning of Apollo’s Heptachord, the lyre of the radiant god, in each of the seven strings of which dwelleth the Spirit, Soul and Astral Body of the Kosmos, whose shell only has now fallen into the hands of modern Science.... Be prudent, we say, prudent and wise, and above all take care what those who learn from you believe in; lest by deceiving themselves they deceive others, ... for such is the fate of every truth with which men are, as yet, unfamiliar.... Let rather the Planetary Chains and other super‐ and sub‐cosmic mysteries remain a dreamland for those who can neither see, nor yet believe that others can_.”

It is to be regretted that few of us have followed the wise advice, and that many a priceless pearl, many a jewel of wisdom, has been cast to an enemy, unable to understand its value, who has turned round and rent us.

“_Let us imagine_”—wrote the same Master to his two “lay chelâs,” as he called the author of _Esoteric Buddhism_ and another gentleman, his co‐ student for some time—“_let us imagine that our earth is one of a group of seven planets or man‐bearing worlds.... [The __‘__seven planets__’__ are the sacred planets of antiquity, and are all septenary.] Now the life‐ impulse reaches A, or rather that which is destined to become A, and which so far is but cosmic dust [a laya‐centre]_ ...” etc.
