First, think of the hand as a gateway to the rest of the body's ecosystem. Each finger and palm coincide with a region of the body (Note: Body mapping applies to the feet as well). You can find a hand (and foot!) map in any guidebook to reflexology, an alternative healing system, like Traditional Chinese Medicine or Ayurvedic medicine. Each health practice uses natural ways to heal and balance the body using organic means, like energy alignment and herbology.
In Eastern medicine traditions, the body contains vital energy centers, which run through the body on meridians, north and south routes from the top of the head through all the appendages.
Within the body, there are seven vertically aligned energy meridians called chakras. The chakras have precise locations, starting at the root chakra (near the base of the spine in the pelvic region) up to the crown chakra (top of the skull). Think of these chakras as vibration highways, strings to an instrument, or waystation hubs on the subway map.
The body's energy centers have a corresponding mudra and mantra, the repeating of word or sound, to hold and hum for vibrational realignment. The mantra is a hummed Sanskrit single syllable, such as om, ham, yam, ram, van, and ram.
Each syllable ricochets and vibrates the body when done with intention. The mudras, combined with the mantras, allow for a greater heart-mind connection. Together, the mudra and mantra promote an inner stillness.
