According to Buddhist texts and most of the wisdom teachings, misidentification is the sole cause of human psychological misery. Those teachings tell us that all personal identification whatsoever is misidentification, and they therefore advise us to seek a state that is clear of all limiting ideas about our true nature.
This is a perfectly understandable misunderstanding of reality, and no cause for blame. Truthfully, those who presented us with these teachings were courageous pioneers in the continuing effort to understand human being and human misery.
But it turns out that it is not identification per se that is the problem. It is the identification with a diseased personality that is the true cause of all the trouble. And that problem turns out to be hard to understand, but really easy to fix.
