In The Secret Doctrine (October 1888) by Helene P. Blavatsky Vol. 1 page 554 till 566 (The Coming Force) is explained that inventor John Worrell Keely already demonstrate his Compound Disintegrator (Picture 1,2,3,4,5,6,7) with the sentence "Had Keely been permitted to succeed, he might have reduced a whole army to atoms in the space of a few seconds as easily as he reduced a dead ox to the same condition". Also inventor Nikola Tesla invented a Death Ray machine, see also an article about him in the New York Times (September 11, 1940).

Keely's Interetheric Force
 To give a greater understanding of events at Sais, that ancient Egyptian city in the Nile delta, The Secret Doctrine by H P Blavatsky relates: "...And how little Herodotus could tell is confessed by himself when speaking of a mysterious tomb of an Initiate at Sais, in the sacred precinct of Minerva. There, he says 'behind the chapel is the tomb of One, whose name I consider it impious to divulge... In the enclosure there are large obelisks and there is a lake near, surrounded with a stone wall in a circle. In this lake they perform, by night, that person's adventures, which they call mysteries. It is well to know that no secret was so well-preserved and so sacred with the ancients as that of their cycles and computations. From the Egyptians down to the Jews it was held as the highest sin to divulge anything pertaining to the correct measure of time. It was for divulging the secrets of the Gods, that Tantalus was plunged into the infernal regions; the keepers of the sacred Sybilline Books were threatened with the death penalty for revealing a word of them.' The Secret Doctrine, Vol II, page 396. While not directly related to the Seven Veils of Sais, the following quotation from The Secret Doctrine, Vol. III, p.132, may afford further insight into what was hidden behind them. "An impenetrable veil of secrecy was thrown over the Occult and Religious Mysteries, after the submersion of the last remnant of the Atlantean Race, some 12,000 years ago, lest they should be shared by the unworthy, and so desecrated. Of these Sciences several have now become exoteric — such as astronomy, for instance, in its purely mathematical and physical aspect." Ed.

"Madame Blavatsky said that the place where she had obtained her secrets still contained great treasures of ancient literature, but that the most important parts of this wisdom had been kept protected from western eyes." [Rudolf Steiner, Lecture: Berlin May 26th, 1904 (GA 89)]
