ATLANTIS- THE LOST CONTINENT

    Atlantis is prophesied to be a large continent which was technologically far advanced, which existed before the sumerian civilization (3000-2500 B.C). The reference is quoted from Plato's dialogues with his disciples and most of the other references are from mostly fictious works and readings by mediums. The most important remarks about Atlantis comes from The Edgar Cayce Readings in which he has repeatedly mentioned the karmic effects of some of the persons he was dealing with to be associated in some way, having previous incarnations in the Atlantis.

 "It is said that when the continent of Mu sank, the oceans of the world lowered drastically as water rushed into the newly formed Pacific Basin. The relatively small islands which had existed in the Atlantic during the time of the Lemurian civilization were left high and dry by the receding ocean. The newly emerged land joined the Poseid Archipelago of the Atlantic Ocean to form a small continent. This continent is called Atlantis by historians today, though its real name was Poseid.

  The continent was supposed to be powered by a large crystal which harnessed the solar energy and this was distributed into smaller powergrids, all having well cut crystals having curious designs. The Atlanteans were supposed to have flying vehicles powered by this solar or atomic energy and these flying saucers were capable of travelling under water also. The Indian puranas and yantra samhita's have a few references where wars between bharata varsha(Indian Soil) and Asvins(Atlanteans) are described, where aerial combat is done with various 'astras' (pointed weapons of the shape of arrow) of various kinds like agni (fire), jala water), and more fierce ones like Brhmastra (Atomic) and pashupatastra (siva's energy- similar to plasmic/cosmic energy) is used and the aerial vehicles were supposedly mostly equipped with solar and atomic energy with rather than thrust and go reaction, it was like nullifying the magnetic field around the hull of the space craft. Also, the flying craft (saucer shaped or mostly cigar shaped) was specifically tuned to be responsive to the thought frequency of the specific mind for whom the vehicle was supposedly made, and any other persons to fly it was difficult for it was to be 'first unlocked by mind' by the owner before another mind could take control. The Deva shilpi called 'Mayan' was specifically recommended for the construction as his crafts were supposed to be the best as also his weapons were. The below given reference is from a recent article about the warfare between the similar Vailixii's owned by the AAtlanteans and Indians with their crafts. 

 "According to Eklal Kueshana, author of "The  Ultimate Frontier," in an article he wrote in 1966, Vailixi were  first developed in Atlantis 20,000 years ago, and the most  common ones are "saucer shaped of generally trapezoidal cross- section with three hemispherical engine pods on the underside."  "They use a mechanical antigravity device driven by engines  developing approximately 80,000 horse power." The Ramayana,  Mahabarata and other texts speak of the hideous war that took  place, some ten or twelve thousand years ago between Atlantis  and Rama using weapons of destruction that could not be imagined  by readers until the second half of this century.
