My therapy involves periods of getting in touch with my body, e.g. tension in my forehead or tightness in my chest, and then as I focus and try to be present with the sensations, words tend to pop into my mind that often yield insights into suppressed feelings and ideas. There's a book that nicely presents the therapy technique named body centered psychotherapy by Ron Kurtz. I wonder if focusing on ones heartbeat employs the same underlying mechanisms that help self-insights happen.
