Throughout those 3 months of dying, his and mine, one of my best teachers was Byron Katie Loving What Is: Four Questions that Can Change Your Life. Her questions became my tools for dismantling the cherished beliefs that had kept me locked into old patterns that no longer served me. She invites us ask ourselves over and over, “Is this true? Can I even prove that it’s true?” Every time the old beliefs surfaced I’d put myself “on the witness stand,” and demand proof that it was true. I lost every time.
