"The experience of dancing constitutes something more than a body in motion. There is a release and a replenishment of psychic energy that leaves one with an oceanic feeling of freedom from which all constraint has fallen away, in which the free play of the emotions in disciplined response to the music has its way. One is infused with a lyrical joy. Little wonder that such feelings have been perceived as reminiscent of the nurturance and protection of the prenatal and infancy stages. However that may be, and whether one dances by oneself or with others, it is the positive reinforcements that one receives from this poetry of motion, this feeling of being in tune with the universe, that is so uplifting and constructively beneficial. It would be difficult to think of any activity of greater therapeutic value." (Montagu, Ashley (1989) Growing Young N.Y.: McGraw Hill pp. 192)
