Sorry, but I have met many Tibetans and even Tibetan lamas and teachers, for the most part their minds are just as infected with worms as ours appear to be.
It's not that we have defilements and they don't. It's more that our culture creates chaotic and confused people. Our religion's credibility collapsed, and our society is complicated and quickly changing. Philosophically, politically, socially, interpersonally, privately, and even intimately our lives are chaotic. The tendency is for people to become either frightened and overwhelmed ot selfish and happy to get their own needs met. Their society was, on the village level, very simple and straightforward. Their religion, which was 100% credible, gave them a way to see their place in the universe, and it was good
. Their educational system took a simple premise and developed it towards true and complete understanding. It's our fundamental chaos that is only expanded/elaborated on by our educational system that they can't get. "How can this person be so intelligent and educated and still be a whack job?" But bless their hearts, they do what they can.
