Natural practice of meditation Hey I just wondered: I met a high intensity theravadin meditator (who teaches it) and he defined the self enlightened as being meditators that no one had to teach. It came naturally, so to speak.

Is it possible to be practicing this untaught meditation but not be self enlightened?
Re. the first paragraph of your question, perhaps the teacher you met was talking about a so-called pratyekabuddha or paccekabuddha (it's useful to know the technical word if you want to read more about it, see also e.g. the 'external links' etc. at the end of that article).
