Zoran,
It is in Infinite Insights volume 1 pages 21, 22 as a footnote. That was written in 1982.
Will Tracy answered the time frame with mentioning the temple was during the 60s not in the 70's. He used some footnotes also.

Bottom of the page he discuss's it. This was his answer to the claim in the 1982 book that EPSr wrote. Will did that in the early 1990s, was one of the good things about the web.
Since I was not there I am only posting it and adding my observations. I read quite a bit as many know. Thought I'd answer the question, Mills did not.
