Infrared, ultrasound, X-rays, the microscopic small... Every child knows that there is much that we cannot perceive, yet it is still real. And there are things that even technical tools cannot show us, but can be recognized with a perception that is attuned to them. This book aims to break the boundaries of our imagination that prevent us from using our 'extrasensory' senses. With many practical exercises, Stefan Brönnle shows us: Anyone can see beyond.
