"Human longing for ritual is deep, and in our culture often frustrated," writes theologian Tom F. Driver in The Magic of Ritual (HarperSanFrancisco, 1991). His simple observation explains the surge of interest in chant and other rediscovered rituals.
Certainly, in a society where many believe singing is something done by others and purchased in the form of concert tickets or a CD, our understanding of the aesthetic and ritual dimensions of the human voice has diminished.
Although we can't prove it, chant, or sacred singing, was probably one of the first expressions of human spirituality. Incorporating a chanting ritual into your yoga practice is easy and, for many, the act of chanting facilitates a greater sense of peace than practicing asanas alone.
