Inescapability is the characteristic of the human mind of being unable to not believe and/or not know something and/or of not simply having the impact of believing and/or knowing something.  In other words, you are always, actually or in effect, locked in to some idea.  Even when you experience a blank mind, you are locked in to something – the impact of the knowledge that you have a blank mind.  Note that, if there were moments of “no lockage,” there would still be “eventual inescapability.”
