 The IBSR Inquiry-based stress reduction intervention, developed by Byron Katie trains subjects to reduce their perceived level of stress by self-inquiry of their thoughts and beliefs connected to stressful circumstances or symptoms. This meditative process, named The Work, enables the participants to identify and question the stressful thoughts that cause their suffering. The core of IBSR is simply four questions and a turnaround, which is a way of experiencing the opposite of what the participant believes. This process is simple, powerful and can be easily implemented in daily life.
