Although Robert Anton Wilson certainly had the ability to listen and to learn from others, he was scathing on the subject of elevating a teacher to the status of a guru. Here is one saying attributed to him: "A disciple is just an asshole looking for a human being to attach itself to."
Here's a story from the New York Times about a Zen teacher who took advantage of his female followers. Here is a sentence:
In the council’s report on Jan. 11, the three members wrote of “Sasaki asking women to show him their breasts, as part of ‘answering’ a koan” — a Zen riddle — “or to demonstrate ‘non-attachment.’ ”
Apparently the teacher also was into groping.
The anecdotes about the Zen teacher are rather reminiscent of the stories about Isaac Asimov that emerged years after Asimov's death. Asimov was a favorite writer of mine, particularly when I was a teenager.
I suspect Asimov would not get away with it now. (He died in 1992). Interesting that science fiction fandom is more enlightened than the world of Zen Buddhism.
