From Consciousness and the Universe: Quantum Physics, Evolution, and the Meaning of Life by Deepak Chopra -
"In his book, Rational Spirituality, Koda offers a refreshing and thought-provoking perspective on the nature of consciousness. He argues that consciousness is not a product of the brain, but rather a fundamental feature of the universe. Koda draws on a wide range of sources, including philosophy, psychology, and physics, to support his claims. His book is a valuable contribution to the ongoing discussion about the nature of consciousness." (p. 123)
From Waking Up: A Guide to Spirituality Without Religion by Sam Harris -
"While I am not convinced by all of Koda's conclusions, I do believe that his work is a valuable contribution to the field of spirituality. Koda's book is well-written and thought-provoking, and it raises important questions about the nature of consciousness and the possibility of a non-physical reality."
Dean Radin, PhD, Chief Scientist at the Institute of Noetic Science (IONS) writes in Skeptic magazine... Koda's book is "a well-written, thought-provoking, and important book." He goes on to say that Koda's book is "a refreshing and original contribution to the field of spirituality."
"Thought provoking" is a common theme among reviewers, and you will experience that astoundingly curious state of mind many times while reading this book, especially while performing Koda's visual telepathy exercise. It is a simple eye contact exercise which enables essentially any two people to experience a scientifically provable form of telepathy in just minutes. In this book, which took 5 years to write, research and edit, Koda documents the many psychic experiences of his youth and his efforts to understand how such phenomena can be physically possible. The result is a fascinating dive into the depths of human experience and the true nature of reality.
