I recommend Serge Kahili King's Dynamind Technique, a simple but versatile and profound healing process that you can learn here.
And you might be amused, as I was, to read the fourth item in the following list!
Four methods of touch are generally used in the Dynamind Technique:
1. Light Tapping.
2. Gentle Vibration.
3. Extended Contact (with light pressure).
4. Extended Contact with humming.
Okay, kids! Get humming! :-D
If you're interested in learning more about King's huna-related teachings, I highly recommend podcaster Kelly Howell's comprehensive interview with him on Brain Sync: Theatre of the Mind.
