All the elements are in the breath, according to the direction which the breath takes: the earth, water, fire, air, and ether. We can taste them in the breath. There are five directions, four outward and one inward. You may say, "What influence can the direction have?" I will say, "If you take a ball and throw it in every direction, the ball will not go equally far at every throw. It will go sometimes further, sometimes not so far." The direction of the breath makes an effect even in our words. Sometimes we say, "Yes, I see," directly. Sometimes we say, "Yes," sarcastically, "I see," and our head is thrown back, the breath comes obliquely, the effect is quite different. If you say, "We cannot feel, perceive the elements in the breath; we do not know where they are," I will say, "This is a science. It cannot be understood in a moment. It is a study."
