Alternative Two
The second alternative is similar to the first but if involves you responding to the body call by sending sound to the specific area. Thus, like Ella Fitzgerald breaking the glass with her voice in the commercial many years ago, so, too, your tone will shatter the energy crystallization the is seeking release.
To prep for this spend some time sending your voice to areas in your body. This works most effectively from the head to the hips. Choose a phonetic (again, experiment here). Starting at a higher pitch allow the voice tone to drop into the body. Paying attention to the specific area, you will know when the voice zeros in on it. It will vibrate. Breathe and stay sounding the spot until you feel it release (it stops calling).
In time and with practice you will be able to direct the voice quickly and effectively to anywhere in that physical range. Use it especially with areas of pain.
Note that the phonetcs of the chakras themselves work best as the phoneme used when the call is in the area of one of the chakras.
