Ken Wilber is not my guru or anything, but he would probably say your teacher has stalled at the "Mean Green Meme," meaning the negative expression of the Green Meme.
This would be a reference to the
Spiral Dynamics model of Clare Graves which is more, well, dynamic than the David Hawkins model, but is another hierarchal model of consciousness development.
BTW, it's very
Green to not like hierarchal models.
I like the
Spiral Dynamics model because it is more flexible, less moralistic, and more realistic, I think, than David Hawkins' model, and allows that people can simultaneously be at different levels in different areas of their lives. A lot of Hawkins' stuff makes sense if you leave out the black and white fundamentalist thinking, and, of course, the pseudoscience.

Hawkins seems to be hoist on his own petard, IMO, which I discussed here:

Ken Wilber and his Mean Green Meme have lots of critics, which you can easily Google, if you're curious. But I had a 'Green' landlady who went through my trash to make sure I recycled every last little thing, which is sorta mean-and-green, if you know what I mean.
I think Spiral Dynamics is a much more organic way of looking at consciousness development than Hawkins' model, and I'm not so green that I don't think there are levels of consciousness, though it's a pretty sticky topic of conversation, of course.
