I agree with your horizontal and polarity-free description of Letting Go aspects of Surrender, however, vehemently deny the use of the idiom Go With The Flow, mainly because of its unfortunate connotation with Riding a Bandwagon. It certainly pollutes the piety of a Sanskrit word (शरणागती )Sharanagati that describes the act of Surrendering.
So the trick is to see it first. Then you can let go. Okay okay. Right now im blind. I know it. Lemme meditate more and find out if i can look more in my experience 🤗
