You will say, "Is the direction the only thing that has influence upon the breath?" There are two other forces that influence it, uruj and nazul, the rise and fall. In the jets of water in a fountain some of the jets rise very high, others less high, others rise only a few inches, according to the force by which they are predestined. So it is with the breath. (Here Murshid speaks of length of life and number of breaths. The first impulse given, the hoop, the clock, and the swing of the pendulum. "Lengthening the breath is life." -Mahmud Ghasnavi.)
