> How do you tell a real Buddhist teacher from a fake one? This is notoriously difficult. Buddhist teachers are extremely reluctant to criticise one another; you won't get a straight answer if you ask "Should I go on a retreat with teacher X?". Ultimately you have to rely on your own intuition, which makes it a bit of a game of dice. > What if you are interested in secular meditation and do not believe Buddhism or ot…
"Vipassana is a set of techniques for destroying the belief that you have an independent self. Not believing you have a self is itself a mark of psychosis." This way of looking at it reveals a clash between Buddhism and mainstream "Western" psychology. If one experiences the self as unreal, the world as unreal, others as unreal, according to some forms of Buddhism you're on your way to enlightenment (if not already t…
I was over-simplifying when I said "destroying the belief that you have an independent self" - the cause of suffering is attachment to the sense of an independent self.

The term "ego" is used in Western discourse about Buddhism, as a cipher for the attachment to the sense of self. That is not what is meant by "ego" in Freudian or Jungian psychiatry (basically, the focus of consciousness). I wish Western Buddhists would stop using that word.
Western psychiatry doesn't pretend to address anything like the state of nirvana. It's mainly concerned with curing pathological conditions. I don't think any reputable psychotherapy traditions propose to take you any further than a condition of being free of the most-obvious kinds of hang-ups (Jung and his followers might be exceptions - I'm not sure - Jung's views were very expansive).
The Abidharma is the closest thing in Buddhism to psychology; it presents a detailed, practical (for meditators) way of thinking about the mind and how it works. It doesn't resemble Western psychology at all.
