Again, I disagree. It's arrogant to say "Hey, X thing I believe in can cure you of Y disease because so many people think it can and you're just ignorant. Nevermind the fact that it's totally untestable or perferms equally to placebo, as long as you feel better it's working!". It's pretty not arrogant to say "Hey, you have a condition that science has at best a limited understanding of, but it might work based on the clinical trials and controlled studies that have been done. It's the best we have to go on, or you could pray."

I think you also mistake "understanding of the universe" for a perceived experience. Just because you did mushrooms at Shambala once doesn't give you a better understanding of anything except maybe why you made some stupid choices in the past.

Why would Yoga be dogmatic? It's exercise.
