By watching the incoming and outgoing breath, its rhythm naturally slows down, thus calming the violent action of heart, lungs, and diaphragm. The heart pumps about seventeen tons of blood a day, and gets no rest at night, hence is the most overworked organ in the body. The ancients knew this method of resting the heart, thus increasing the span of life and also liberating a tremendous amount of life power, which revitalizes the cells of the body.
