My 92-year-old mother is going blind, so she needs assistance to walk. She can't accurately assess what is there, so she can't walk safely.
When I was new, I was blinded by my addiction. Except I thought I could see. I therefore navigated my life based on a false perception of reality.
The answer was to recognise that I could not see right, to trust others' perception of reality over my own, and to let them guide my actions.
This is what surrender is.
Stop believing my own assessment; adopt someone else's; navigate by their compass, not mine.
Eventually, the mind comes back, and then I can assess and navigate myself.
But that comes later.
