Inner emptiness is one of our greatest fears. We even write living wills to prevent situations like dementia or coma because we are so terrified of their alleged emptiness. But inner emptiness can also be advantageous and fruitful, as Zen masters have long understood. Through music, meditation, focus, or even sex, we can achieve this state. Our brain actually enjoys emptiness because it makes us joyful. Leading brain scientist Niels Birbaumer explores the joy of emptiness and how we might benefit from it. He shows how to go beyond your brain's innate alertness and stop thinking, a talent that is more crucial than ever in our increasingly hectic environment.
