I wonder if this practice, very simple and needs nothing but the breath and voice, is a way of purifying the body through vibration.
I can say that since I have started practicing, there is a notable change in my ability to focus, in organizing thought, and in challenging troubling emotions. As a stay-at-home father of three little girls, it is imperative that I get myself together as quickly as possible, as that they need a dad that is 100%. They need a father who is focused, attentive, sensitive, and able to make rational decisions and remain calm should an emergency arise.
