Not to take away from that thought of the brain being important, because without it, we are veggie dip, but what I want to offer is the opposite:

When we swing the club without fear (kind of like LP42's "trust"), you have now taken a leap of faith that your preshot, practice and preperation up to this magic moment of taking the club back is going to happen exactly the way you expect it to go.

Trying to "make" it happen while you are swinging...well, it's just too late. Turn off all the worry, fear and analytical encomerments and you will see a free swing that has it's best chance of success.
