From the Foreword by Philip Dossick:

In his extraordinary autobiography and other writings, Tesla’s personal descriptions of his creative process give us vital insights into his phenomenal accomplishments. He wrote, “For many years—my life was nothing short of continuous rapture—due to the appearance of images, flashes of light, and strange voices I felt were actually divine guidance from another realm.”

He became convinced they were extraterrestrial in nature; messages from “another world.”

“My ear barely caught signals coming in regular succession which could not have been produced on earth…”

In 1901, Nikola Tesla published an article in Collier's Weekly Magazine entitled, "Talking With The Planets."

In it, the editor wrote:

Mr. Nikola Tesla has accomplished some marvelous results in electrical discoveries. Now, with the dawn of the new century, he announces an achievement which will amaze the entire universe, and which eclipses the wildest dream of the most visionary scientist. He has received communication, he asserts, from out the great void of space: a call from the inhabitants of Mars, or Venus, or some other sister planet! And, furthermore, noted scientists like Sir Norman Lockyer are disposed to agree with Mr. Tesla in his startling deductions."

This book contains the entire article, as well as the complete text of Nikola Tesla's splendid Autobiography.

[Nikola Tesla’s groundbreaking inventions assured his place as one of the greatest geniuses of modern times, without whom our radio, television, radar, automobile ignition, telephone wireless communication, AC power generation, remote control, lasers, and medical x-rays would all have been impossible.]
