Nikola Tesla remains one of the most enigmatic scientists of our time, whose work greatly shaped modern technological civilization.

But beyond being a genius inventor, he was also a particularly insightful thinker about the nature and potential of humanity, the challenges and dangers of technological progress, the properties of energy and the Universe, as well as art, politics, ethics, and religion.

His views on all these crucial issues remain remarkably relevant today, and no one is more suited to convey his words to us than himself, through articles and writings presented in this book, forming a kind of "spiritual legacy".
