I don't think he tapped anything "off-planet". I do think that he was a lot more flexible in his thinking (at least in print) than later in his life. His unwillingness to be scientific in his approach (or perhaps his lack of understanding of what the scientific approach was) means that most of what he wrote has to be taken with a grain (or a shaker) of salt.
The complexity of his approach grew over time. Likely, this was an income generating scheme (keep the marks buying), but also may have been indicative of declining access to the SIMPLICITY of the original understanding.
I trust the Pilot more than I trust Ron, but both are still talking the language of religion when the language of science is more appropriate.
