Healing with laughter was used by Norman Cousins to heal himself and humor was used by Dr. Patch Adams while developing his vision for a new model health care design. As serious as his work is, surgeon and cancer specialist, humor is also an important part of Dr. Bernie Siegel presentations. Now, Dr. Madan Kataria uncovered a type of yoga practice called hasya yoga that produced lasting deep laughter and he is teaching it around the world. The website is a great resource where you can find links to local groups and recorded laugh sessions.
