There's something to be said about trust, flow, surrender, and that faith thingy.
Trust and faith are like two brothers neither one understanding with their brains but feeling in their guts. Faith is a little more in the feeling region while trust might be more in the intellect, the observation region.
Surrender is what happens when you've had enough swimming against the flow. Surrender and flow are like a couple. They're different from one another. They can clash at first but after many years and decades, they understand and work together. Surrenders into the flow. How many men have felt that with their wives and parters?
Didn't Buddha say once he was enlightened that it was all so silly? There was no effort to be made. Isn't Satori a flash? No effort there.
