Byron Katie's Work Reduces Anxiety and Procrastination.

Study suggests that inquiry-based stress-reduction can help reduce anxiety and procrastination.

Byron Katie, a non-dual teacher, wrote a book called Loving What is: Four Questions That Can Change Your Life (2003), which laid out her method of self inquiry.  The inquiry follows this pattern:

• “Is this thought true?”
• “Can you absolutely know that this thought is true?”.
• “How do you react, what happens when you have this thought?”
• “Who would you be without the thought?”
