It is "personality" that proscribes what stays, or what goes... when passing through the sifter that is one's own mind. Through common threads of association or repetition, what enters can be captured and kept. But what truly becomes the heart of the man...what permeates each softened cell and changes it's structure....is a matter of his formed ( or malformed) character and personality. Your vortex of action or concession is a very personal one. Perhaps your last choice of free-will has already been made..
"You only have power over people as long as you don't take everything from them. But when you've robbed a man of everything, he's no longer in your power....he's free again." (Alexander Solzhenitsyn, In The First Circle 1968).
