We have now to deal with the exercises in Prânâyâma. We have seen that the first step, according to the Yogis, is to control the motion of the lungs. What we want to do is to feel the finer motions that are going on in the body. Our minds have become externalised, and have lost sight of the fine motions inside. If we can begin to feel them, we can begin to control them. These nerve currents go on all over the body, bringing life and vitality to every muscle, but we do not feel them. The Yogi says we can learn to do so. How? By taking up and controlling the motion of the lungs; when we have done that for a sufficient length of time, we shall be able to control the finer motions.
We now come to the exercises in Pranayama. Sit upright; the body must be kept straight. The spinal cord, although not attached to the vertebral column, is yet inside of it. If you sit crookedly you disturb this spinal cord, so let it be free. Any time that you sit crookedly and try to meditate you do yourself an injury. The three parts of the body, the chest, the neck, and the head, must be always held straight in one line. You will find that by a little practice this will come to you as easy as breathing. The second thing is to get control of the nerves. We have said that the nerve centre that controls the respiratory organs has a sort of controlling effect on the other nerves, and rhythmical breathing is, therefore, necessary. The breathing that we generally use should not be called breathing at all. It is very irregular. Then there are some natural differences of breathing between men and women.
The first lesson is just to breathe in a measured way, in and out. That will harmonise the system. When you have practiced this for some time, you will do well to join to it the repetition of some word as “Om,” or any other sacred word. In India we use certain symbolical words instead of counting one, two, three, four. That is why I advise you to join the mental repetition of the “Om,” or some other sacred word to the Pranayama. Let the word flow in and out with the breath, rhythmically, harmoniously, and you will find the whole body is becoming rhythmical. Then you will learn what rest is. Compared with it, sleep is not rest. Once this rest comes the most tired nerves will be calmed down, and you will find that you have never before really rested.
The first effect of this practice is perceived in the change of expression of one’s face; harsh lines disappear; with calm thought calmness comes over the face. Next comes beautiful voice. I never saw a Yogi with a croaking voice. These signs come after a few months’ practice. After practicing the above mentioned breathing for a few days, you should take up a higher one. Slowly fill the lungs with breath through the Idâ, the left nostril, and at the same time concentrate the mind on the nerve current. You are, as it were, sending the nerve current down the spinal column, and striking violently on the last plexus, the basic lotus which is triangular in form, the seat of the Kundalini. Then hold the current there for some tune. Imagine that you are slowly drawing that nerve current with the breath through the other side, the Pingalâ, then slowly throw it out through the right nostril. This you will find a little difficult to practice. The easiest way is to stop the right nostril with the thumb, and then slowly draw in the breath through the left; then close both nostrils with thumb and forefinger, and imagine that you are sending that current down, and striking the base of the Sushumnâ; then take the thumb off, and let the breath out through the right nostril. Next inhale slowly through that nostril, keeping the other closed by the forefinger, then close both, as before. The way the Hindus practice this would be very difficult for this country, because they do it from their childhood, and their lungs are prepared for it. Here it is well to begin with four seconds, and slowly increase. Draw in four seconds, hold in sixteen seconds, then throw out in eight seconds. This makes one Pranayama. At the same time think of the basic lotus, triangular in form; concentrate the mind on that centre. The imagination can help you a great deal. The next breathing is slowly drawing the breath in, and then immediately throwing it out slowly, and then stopping the breath out, using the same numbers. The only difference is that in the first case the breath was held in, and in the second, held out. This last is the easier one. The breathing in which you hold the breath in the lungs must not be practiced too much. Do it only four times in the morning, and four times in the evening. Then you can slowly increase the time and number. You will find that you have the power to do so, and that you take pleasure in it. So very carefully and cautiously increase as you feel that you have the power, to six instead of four. It may injure you if you practice it irregularly.
Of the three processes for the purification of the nerves, described above, the first and the last are neither difficult nor dangerous. The more you practice the first one the calmer you will be. Just think of “Om,” and you can practice even while you are sitting at your work. You will be all the better for it. Some day, if you practice hard, the Kundalini will be aroused. For those who practice once or twice a day, just a little calmness of the body and mind will come, and beautiful voice; only for those who can go on further with it will Kundalini be aroused, and the whole of nature will begin to change, and the book of knowledge will open. No more will you need to go to books for knowledge; your own mind will have become your book, containing infinite knowledge. I have already spoken of the Ida and Pingala currents, flowing through either side of the spinal column, and also of the Sushumna, the passage through the centre of the spinal cord. These three are present in every animal; whatever being has a spinal column has these three lines of action. But the Yogis claim that in an ordinary man the Sushumna is closed; its action is not evident while that of the other two is carrying power to different parts of the body.
The Yogi alone has the Sushumna open. When this Sushumna current opens, and begins to rise, we get beyond the sense, our minds become supersensuous, superconscious — we get beyond even the intellect, where reasoning cannot reach. To open that Sushumna is the prime object of the Yogi. According to him, along this Sushumna are ranged these centres, or, in more figurative language, these lotuses, as they are called. The lowest one is at the lower end of the spinal cord, and is called Mulâdhâra, the next higher is called Svâdhishthâna, the third Manipura, the fourth Anâhata, the fifth Vishuddha, the sixth Âjnâ and the last, which is in the brain, is the Sahasrâra, or “the thousand-petalled”. Of these we have to take cognition just now of two centres only, the lowest, the Muladhara, and the highest, the Sahasrara. All energy has to be taken up from its seat in the Muladhara and brought to the Sahasrara. The Yogis claim that of all the energies that are in the human body the highest is what they call “Ojas”. Now this Ojas is stored up in the brain, and the more Ojas is in a man’s head, the more powerful he is, the more intellectual, the more spiritually strong. One man may speak beautiful language and beautiful thoughts, but they, do not impress people; another man speaks neither beautiful language nor beautiful thoughts, yet his words charm. Every movement of his is powerful. That is the power of Ojas.
Now in every man there is more or less of this Ojas stored up. All the forces that are working in the body in their highest become Ojas. You must remember that it is only a question of transformation. The same force which is working outside as electricity or magnetism will become changed into inner force; the same forces that are working as muscular energy will be changed into Ojas. The Yogis say that that part of the human energy which is expressed as sex energy, in sexual thought, when checked and controlled, easily becomes changed into Ojas, and as the Muladhara guides these, the Yogi pays particular attention to that centre. He tries to take up all his sexual energy and convert it into Ojas. It is only the chaste man or woman who can make the Ojas rise and store it in the brain; that is why chastity has always been considered the highest virtue. A man feels that if he is unchaste, spirituality goes away, he loses mental vigour and moral stamina. That is why in all the religious orders in the world which have produced spiritual giants you will always find absolute chastity insisted upon. That is why the monks came into existence, giving up marriage. There must be perfect chastity in thought, word, and deed; without it the practice of Raja-Yoga is dangerous, and may lead to insanity. If people practice Raja-Yoga and at the same time lead an impure life, how can they expect to become Yogis?
