Mind is the barrier. Nothing else is hindering you from truth, just your own mind. Mind surrounds you like a film, like a movie that goes on and on, and you remain engrossed in it, fascinated by it. It is a fantasy that surrounds you, a continuous story that goes on and on. And because you are so fascinated by it, you go on missing that which is. And mind is not; it is only a fantasy, it is only a faculty for dreaming.
Mind is nothing but dreams and dreams -- dreams of the past, dreams of the future, dreams of how things should be, dreams of great ambitions, achievements. Dreams and desires, that is the stuff mind is made of. But it surrounds you like a China Wall. And because of it the fish remains unaware of the ocean.
