So, some of the disciples of Ajahn Chah believe he had telepathic powers.
Ajahn Jayasaro tells an anecdote about how Ajahn Chah read someone's mind that they were really hungry and going to take more rice than usual.
I recall listening to an Ajahn Brahm dhamma talk where he says that Ajahn Chah was answering someone's questions of which they told Brahm was jibberish, but made perfect sense to Brahm because he said Chah was answering his
questions by reading his
mind. I can't find that talk now though.
Regardless, it disappoints me that the people involved in these anecdotes did not simply ask Chah whether or not he was telepathic. (What's the harm in asking?) Or, in the case of Jayasaro, think that there may be more plausible explanations other than his teacher having extraordinary superpowers. (Maybe Chah knew that the disciples was sick for a couple days prior and would probably be hungry that day?)
I'd imagine the whole telepathy thing is just a byproduct of students' romantic, mystical ideations about their teacher, and not a real phenomenon.
