Before there was any public disclosure of the U.S. Government's Remote Viewing Research, Lloyd F. Hopkins developed one of the most successful training programs ever for expanding Human Awareness beyond the five senses. His motivation was the exploration of expanded human consciousness, and his desire to help blind people see without eyes. This is the only book that Mr. Hopkins published on his work.

I know a man who trained others to do this.

Very rare to find this. Good addition for the Archivist here, if you see this, Fren :)
