On a recent Yoga intensive with Donna Farhi, she taught us a beautiful chant, the Ayur Mantra. This is a mantra for health and nourishment. It can also be practiced with the ancient art of nyasa, a type of mudra practice, where the placing of the mantra on or around the body is said to be beneficial to the nourishment and protection of the psyche.
Each line from The Ayur Mantra maybe accompanied by a Mudra. Donna recently posted this video on YouTube – a great chant to learn.
 
from the Taittiriya Aranyaka IV.2
You can also just hear Donna chant Ayur Mantra (apologies for the hissy sound quality – it was recorded simply with my mp3 player):
