Discovering Consciousness is a pure joy. We dissolve in something much bigger that we are and this give us an immense feeling of freedom and safety. It is so vast and silent that with the words we can touch only its shade. Mind creates distortion between perception and experience. The more we are identified with some rigid ideas, the thicker is the mind and the bigger is distortion.
Mental health depends on the thickness of the mind.
Unless someone can watch its mind he can not go insane because watching is the function of the consciousness that is the background of mental health. The person that has lost its capacity to watch the mind, has lost its mental health. All kinds of nationalism and religious fundamentalism are creating such mental distortion that the contact with consciousness is gone. Watching is a safe method to dive into the individual and collective unconscious and clean it of all social and religious rigid mental structures that does not allow us to enter into consciousness. Few thousands years ago we have been living by hunting wild animals and the hunting instinct it still alive.
