Very well said mind is just the ability of person to think and reason, it is the brain which is in human head. And as said in the movie lucy starring scarlett johansson... All social systems we’ve put into place are a mere sketch: “one plus one equals two”, that’s all we’ve learned, but one plus one has never equaled two — there are in fact no numbers and no letters, we’ve codified our existence to bring it down to human size, to make it comprehensible, we’ve created a scale so we can forget its unfathomable scale. Time is the only true unit of measure, it gives proof to the existence of matter, without time, we don’t exist.”
