It was only the definite need to explain odd actions that forced the disclosure to my wife. She accepted it reluctantly because there was no other re… - Robert Monroe

In non-physical trips to Locale II, often there is a "layer" or area which one must pass through...It is a gray-black hungry ocean where the slightest motion attracts nibbling and tormenting beings... If you move slowly and do not react to the curious "fish" who come to investigate, you pass through without much incident. Move violently and fight back, then more excited denizens come rushing in to bite, pull, push, shove.
Could this be the borders of hell? It is easy to conclude that a momentary penetration of this nearby layer would bring "demons" and "devils" to mind as the chief inhabitants. They seem subhuman, yet have an evident ability to act and think independently. Who and what are they? I don't know. I haven't taken the trouble to stay there long enough to find out. Only by terrified trial and error did I find the method to pass through in reasonable peace.

The primary purposes for the release and publication of the material contained here are (i) that through dissemination as widely as possible, some other human being—perhaps just one—may be saved from the agony and terror of trial and error in an area where there have been no concrete answers; that he may have comfort in the knowledge that others have had the same experiences; that he will recognize in himself the phenomenon and thus avoid the trauma of psychotherapy, or at the worst, mental breakdown and commitment to a mental institution; and (2) that tomorrow or in the years to come, the formal, accepted sciences of our culture will expand their horizons, concepts, postulates, and research to open wide the avenues and doorways intimated herein to the great enrichment of man's knowledge and understanding of himself and his complete environment. If one or both of these aims are served, whenever and wherever it may be, this is sufficient reward indeed.

I discovered the existence of an underground... This underground only occasionally intermingles in part with the worlds of business, science, politics, academia, and the so-called arts... it definitely...infiltrates all of Western civilization.... one thing is usually certain: members of this underground who are respected in their communities don't talk about the interest or beliefs that qualify them for membership unless they know you too are in the club. They have learned from experience that to be outspoken brings censure —from their ministers, customers, employers, or even friends... They are found in all walks of life: scientists, psychiatrists, physicians, housewives, college students, businessmen, teenagers, and at least a few ministers in formal religions... They gather in small groups, quietly and often semi-secretly... usually discuss affairs of the underground only with other members... All are to some degree emotionally and intellectually dedicated to a cause. Finally, the underground has its own literature, language, technology, and to some extent demigods.
