Thank you very much for this link. It put to words some concepts I had been somewhat cognizant of, but hadn't really been able to fully explore.
An acquaintance of mine, who had come to me for an introduction to mindfulness practice, was sidelined by an unsettling revelation much in the way that Brasington described. Sure enough, parental trauma played a role. I wish I had thought to refocus her on self-focused metta meditation, or otherwise "getting grounded" before we lost contact. I'll save this for her in case our paths cross again.
I find it interesting too that they noted how big-picture thinking can falter in the period after heavy concentration — another curious point I'll keep an eye out for in myself. They mention the example of some people falling into temporary space-cadet-mode after a long meditation session, circa ~22min. I've never thought of it as an issue (of course, I've never left behind my shoes either), but I can see how it would be worth talking about the "Yogi mind" experience if it commonly plays out like that, and some new practitioners find it unsettling.
