The freedom of an individual depends upon that individual's freedom to alter his considerations of space, energy, time and life and his roles in it. If he cannot change his mind about these, he is then fixed and enslaved amidst barriers such as those of the physical universe, and barriers of his own creation. Man thus is seen to be enslaved by barriers of his own creation. He creates these barriers himself, or by agreeing with things which hold these barriers to be actual.
