I met him a few year ago in Maui.
He's actually a very nice man.
What he does is teach good ideas from others, and promotes hope.
There is something missing in his work, though. And that is that most people who sell hope, do not acknowledge that human change, or "transformation" is actually very, very hard.
People, mostly, don't change.
Ergo, most of the packed house is filled with people that are already pre-disposed to these good ideas (and to be sure they are good ideas, rooted in age old traditions, spiritual paths, and ancient philosophies) and promotions of hope.
Your response to what you see in him...is basically, you.
Perception, is, predominantly, PROJECTION. So if you see him as a snake oil salesman, or you have a negative response to him... You are basically seeing yourself, outing yourself for your own negativity.
Other people see him on TV and just go "oh, hope that works for those people," have a benevolent or benign response, and click on over to whatever.
That said, when I met him (ran into him twice by his beach condo) I told him that I appreciated his efforts, but that there was something missing in his work."
I was just speaking my truth. And I didn't tell him what I felt was missing, cos I wanted him to be curious. --Basically, because if he embodied what he teaches, his intuition would tell him what was missing. I did tell him, that was was missing could lead him to another chapter in a book, or another book.
This all said, Dyer's work is essentially benign, good stuff, if you are open to it, from good sources, presented pretty well. Just don't go overboard.
You want to be skeptical? Be skeptical of Dr. Amen's pbs specials...
