As my partner and I got to talking about guns, elements, and doshas, somewhere in between we started analyzing Marvel Avengers their elements, and doshas. It was supremely fun and so unexpected! Like Thanos appears to have so much earth in him and how rigid he is, quicksilver must have more wind and his ever-so-moving fast nerve impulses, Dr. Strange starts to have so much pitta and slowly lets it go as he accepts the flow, how all most all avengers might have fire in them with all that ambition, purpose, and their age, etc.
He still needs to listen to your webinar, and I am sure we will discuss their elements and gunas a few layers deeper once he does that.
