We will now take up the Psychic phase of the Yogi Science of Breath in the shape of a series of exercises, each exercise carrying with it its explanation. You will notice that in each exercise rhythmic breathing is accompanied with the instructions to "carry the thought" of certain desired results. This mental attitude gives the Will a cleared track upon which to exercise its force. We cannot, in this work, go into the subject of the power of the Will, and must assume that you have some knowledge of the subject. If you have no acquaintance with the subject, you will find that the actual practice of the exercises themselves will give you a much clearer knowledge than any amount of theoretical teaching, for as the old Hindu proverb says, "He who tastes a grain of mustard seed knows more of its flavor than he who sees an elephant load of it." (1) GENERAL DIRECTIONS FOR YOGI PSYCHIC BREATHING. The basis of all Yogi Psychic Breathing is the Yogi Rhythmic Breath, instruction regarding which we gave in our last chapter. In the following exercises, in order to avoid useless repetition, we will say merely, "Breathe Rhythmically," and then give the instruction for the exercise of the psychic force, or directed Will power working in connection with the rhythmic breath vibrations. After a little practice you will find that you will not need to count after the first rhythmic breath, as the mind will grasp the idea of time and rhythm and you will be able to breathe rhythmically at pleasure, almost automatically. This will leave the mind clear for the sending of the psychic vibrations under the direction of the Will. (See the following first exercise for directions in using the Will.) (2) PRANA DISTRIBUTING.
