Science and the Inner Experience by Edgar Mitchell
In 1971, Edgar Mitchell became the sixth human to walk on the moon. These two audio recordings of presentations he gave some 20 years later about his experience, are nothing short of life-changing for those open to truly hearing his description of that experience and how it changed his life.
I enjoyed Edgar Mitchell's presentation on this interesting subject very much. Since he is an astronaut who went to the moon I highly respect his opinion. In addition, Mitchell explains a complicated subject in a manner that is easy for the ordinary person to understand. I highly recommend all of Edgar Mitchell';s lectures.
