The process of spiritual discovery became the focus of Dr. Heinemann's life in the early 1970ies, when he and his wife attended classes and seminars led by the late Dr. Harry and Emilia Rathbun. Their work focused on the mission and book by the late Dr. Henry Burton Sharman, Jesus as Teacher. The Rathbun's own lives' demonstration that the messenger must be congruent with the message has left a life-changing impression on Klaus.

Other spiritual teachers who profoundly impacted Dr. Heinemann's life include the Rev. Dr. Ron Roth , who, perhaps more convincingly than any other teacher he had encountered at the time, emphasized that even the most profound teaching has but little impact on a person's personal growth unless it sinks from the level of the mind to the level of the heart.

With his science background, Klaus has followed a calling to communicate that the spiritual realm is no less "real" than the pyhsical reality familiar to us. In his book, "Expanding Perception - consciousness, wisdom, compassion, love," he presents how even a person with a formal natural sciences background can come to the expanded perception/view that "there is more to Life than life."

In his latest book, "The Orb Project," co-authored with Dr. Miceal Ledwith and with an extended foreword by Dr. William A. Tiller, Klaus discusses digital photographs that contain clear and irrefutable evidence of phenomena that cannot be explained on the basis of conventional physics.
