Indeed, we see the world through the prism of our images, sounds, thoughts that refer to what we have already experienced. It is therefore important to be aware of. Bandler also tells us the means to change some of our internal perceptions such as inner voices, images that keep coming back in our head. as it says, it sounds very simple, but in practice you have to be able to concentrate to create our inner cinema in our idea. it's not always so easy. A test according to individual capacity to juggle these concepts.
