I read the quotations first
Format: Hardcover
Of all the stories I have read about those who experienced extraterrestrial life, and all those who told those stories, Billy Meier's story is the most authentic. This book is a beautifully written and photographed narrative of Meier's relationship with various people from the stars, over a period of time. Billy himself reminded me of my best friends in the 1960's and 70's--quiet and kind. But the most remarkable part of this book, apart from the extraordinary photographs, is that there are quotations from the extraterrestrial visitors themselves, which are worth reading, in order. Yes, you might still not believe this happened, but you cannot help but absorb insights in those quotations. You will not forget them.

A Civilization in Transition: Can Humans Make the "Jump" to Hyperspace?
Format: Hardcover
Though there is ample evidence to suggest that humanity has been visited by "off-planet" beings or relatives since as far back as any recorded history in stone or on paper, with the advent of technologies bringing us closer to an enlightenment or a destruction, UFO/UAP events seem to becoming more frequent. And more accepted. When UFO...CONTACT FROM THE PLEIADES v I and II were first published 45 years ago few people had a personal computer in their homes let alone any digital technology whatsoever. There were gains in human rights protections along with ecological study and the awareness of the importance to "love our Mother." (Earth) So it may not be so unreal to consider that one specific human, a farmer in rural Switzerland was chosen for multiple contact events and allowed to capture photographs, audio recordings, films and even metallic samples from OP visitors for the purpose of helping humanity expand its consciousness to the next level.
This reissue tells such a story with vivid photography, detailed analysis and skilled reporting having used the most advanced non-civilian equipment available at the highest levels in its day. Furthermore, time has only affirmed that none of the photographs or video from the Billy Meier case have proved to be fake or forged in any known way.
This is the book for searchers interested in the "nuts and bolts" of ufology. And yet...
Whether you believe in UFOs or off-planet visitors is really beside the point here. The deeper point - and the not so hidden purpose revealed through the messages given to Billy Meier from Semjase, a Pleiadean traveler who contacted Meier over 100 times in the 1970s - is to consider if each one of us is capable of suspending disbelief long enough to be curious, which takes an open heart. And if we open our hearts, how can we do harm to ourselves, our planet, or others in the universe? And if we can achieve "do no harm" what else could we achieve? Hyperspace? Telepathy? A humane civilization where no one goes hungry or homeless? The point is whether or not we are ready, collectively, to expand our consciousness.
After reading this book, I want to take that leap!

No doubt the subject of UFO's and ET's is a challenging subject. But the Billy Meier story is certainly one of the very best. This book is masterwork that warrants the highest rating. The photos are extraordinary and the story line is superb. Buy a copy or several for yourself and for gifts .
