RE: Moving between absolute thrills and deadly boredom - sounds familiar? Then you might need a little exercise in finding middle ground - a nice resolution for 2018.
I absolutely agree with your assessment of the danger of trying to understand and to judge/know what is going on. In my practise (I'm training and soon to be an art therapist) I use the ACT theory (Acceptance & Commitment Theory) that might interest you as well, as it draws from both Western psychology and Buddhist/Eastern knowledge. It focusses on acceptance not as a simply letting it go / not being bothered - but as a truly facing of what is, what is going on, and accepting that it is part of who you are at this moment, and then committing not to an avoidance or short-term resolution, but to the values that you find worth dealing with. I find it interesting when I work with clients that having this attitude myself, protects me from going with judgments about myself, the client, situations, etc.
This was meant to just add something, not seeing things different from you, I think, very nice! Makes me happy to read your words that are so true to me.
So we are walking the same path, don't we? :)
I must admit that it is a very huge challenge and I realize every day that I must practice a lot to achieve this ideal.
"Art therapist" is an interesting term creation. Just yesterday I read an article from @abigail-dantes: https://steemit.com/psychology/@abigail-dantes/is-psychology-a-science
which raises the question if psychology is a science. But go and look yourself.
