One of the primary training instruments of yoga is absurdly simple—the breath.
The life-force, the prana that animates us is carried on the breath, and this life-force emerges directly out of the fabric of Ishvara, infinite consciousness, and arises inside the breath of every living thing. Infinite truth arising within us, as us, with every breath.
Twenty-one thousand breaths every day—if every breath is conscious, you can unleash unimaginable spiritual force within yourself. That is the training. To consciously draw the awakening principle into yourself with every breath, to feel it capture the form of your very being, infusing the dynamic of truth into every cell. The gravity that arises from this tells you that you have found the thread of the truth within your self.
