The science of Raja-Yoga, in the first place, proposes to give us such a means of observing the internal states. The instrument is the mind itself. The power of attention, when properly guided, and directed towards the internal world, will analyse the mind, and illumine facts for us. The powers of the mind are like rays of light dissipated; when they are concentrated, they illumine. This is our only means of knowledge. Everyone is using it, both in the external and the internal world; but, for the psychologist, the same minute observation has to be directed to the internal world, which the scientific man directs to the external; and this requires a great deal of practice. From our childhood upwards we have been taught only to pay attention to things external, but never to things internal; hence most of us have nearly lost the faculty of observing the internal mechanism. To turn the mind as it were, inside, stop it from going outside, and then to concentrate all its powers, and throw them upon the mind itself, in order that it may know its own nature, analyse itself, is very hard work. Yet that is the only way to anything which will be a scientific approach to the subject.
What is the use of such knowledge? In the first place, knowledge itself is the highest reward of knowledge, and secondly, there is also utility in it. It will take away all our misery. When by analysing his own mind, man comes face to face, as it were, with something which is never destroyed, something which is, by its own nature, eternally pure and perfect, he will no more be miserable, no more unhappy. All misery comes from fear, from unsatisfied desire. Man will find that he never dies, and then he will have no more fear of death. When he knows that he is perfect, he will have no more vain desires, and both these causes being absent, there will be no more misery — there will be perfect bliss, even while in this body.
There is only one method by which to attain this knowledge, that which is called concentration. The chemist in his laboratory concentrates all the energies of his mind into one focus, and throws them upon the materials he is analysing, and so finds out their secrets. The astronomer concentrates all the energies of his mind and projects them through his telescope upon the skies; and the stars, the sun, and the moon, give up their secrets to him. The more I can concentrate my thoughts on the matter on which I am talking to you, the more light I can throw upon you. You are listening to me, and the more you concentrate your thoughts, the more clearly you will grasp what I have to say.
How has all the knowledge in the world been gained but by the concentration of the powers of the mind? The world is ready to give up its secrets if we only know how to knock, how to give it the necessary blow. The strength and force of the blow come through concentration. There is no limit to the power of the human mind. The more concentrated it is, the more power is brought to bear on one point; that is the secret.
It is easy to concentrate the mind on external things, the mind naturally goes outwards; but not so in the case of religion, or psychology, or metaphysics, where the subject and the object, are one. The object is internal, the mind itself is the object, and it is necessary to study the mind itself — mind studying mind. We know that there is the power of the mind called reflection. I am talking to you. At the same time I am standing aside, as it were, a second person, and knowing and hearing what I am talking. You work and think at the same time, while a portion of your mind stands by and sees what you are thinking. The powers of the mind should be concentrated and turned back upon itself, and as the darkest places reveal their secrets before the penetrating rays of the sun, so will this concentrated mind penetrate its own innermost secrets. Thus will we come to the basis of belief, the real genuine religion. We will perceive for ourselves whether we have souls, whether life is of five minutes or of eternity, whether there is a God in the universe or more. It will all be revealed to us. This is what Raja-Yoga proposes to teach. The goal of all its teaching is how to concentrate the minds, then, how to discover the innermost recesses of our own minds, then, how to generalise their contents and form our own conclusions from them. It, therefore, never asks the question what our religion is, whether we are Deists or Atheists, whether Christians, Jews, or Buddhists. We are human beings; that is sufficient. Every human being has the right and the power to seek for religion. Every human being has the right to ask the reason, why, and to have his question answered by himself, if he only takes the trouble.
So far, then, we see that in the study of this Raja-Yoga no faith or belief is necessary. Believe nothing until you find it out for yourself; that is what it teaches us. Truth requires no prop to make it stand. Do you mean to say that the facts of our awakened state require any dreams or imaginings to prove them? Certainly not. This study of Raja-Yoga takes a long time and constant practice. A part of this practice is physical, but in the main it is mental. As we proceed we shall find how intimately the mind is connected with the body. If we believe that the mind is simply a finer part of the body, and that mind acts upon the body, then it stands to reason that the body must react upon the mind. If the body is sick, the mind becomes sick also. If the body is healthy, the mind remains healthy and strong. When one is angry, the mind becomes disturbed. Similarly when the mind is disturbed, the body also becomes disturbed. With the majority of mankind the mind is greatly under the control of the body, their mind being very little developed. The vast mass of humanity is very little removed from the animals. Not only so, but in many instances, the power of control in them is little higher than that of the lower animals. We have very little command of our minds. Therefore to bring that command about, to get that control over body and mind, we must take certain physical helps. When the body is sufficiently controlled, we can attempt the manipulation of the mind. By manipulating the mind, we shall be able to bring it under our control, make it work as we like, and compel it to concentrate its powers as we desire.
According to the Raja-Yogi, the external world is but the gross form of the internal, or subtle. The finer is always the cause, the grosser the effect. So the external world is the effect, the internal the cause. In the same way external forces are simply the grosser parts, of which the internal forces are the finer. The man who has discovered and learned how to manipulate the internal forces will get the whole of nature under his control. The Yogi proposes to himself no less a task than to master the whole universe, to control the whole of nature. He wants to arrive at the point where what we call “nature’s laws” will have no influence over him, where he will be able to get beyond them all. He will be master of the whole of nature, internal and external. The progress and civilisation of the human race simply mean controlling this nature.
Different races take to different processes of controlling nature. Just as in the same society some individuals want to control the external nature, and others the internal, so, among races, some want to control the external nature, and others the internal. Some say that by controlling internal nature we control everything. Others that by controlling external nature we control everything. Carried to the extreme both are right, because in nature there is no such division as internal or external. These are fictitious limitations that never existed. The externalists and the internalists are destined to meet at the same point, when both reach the extreme of their knowledge. Just as a physicist, when he pushes his knowledge to its limits, finds it melting away into metaphysics, so a metaphysician will find that what he calls mind and matter are but apparent distinctions, the reality being One.
The end and aim of all science is to find the unity, the One out of which the manifold is being manufactured, that One existing as many. Raja-Yoga proposes to start from the internal world, to study internal nature, and through that, control the whole — both internal and external. It is a very old attempt. India has been its special stronghold, but it was also attempted by other nations. In Western countries it was regarded as mysticism and people who wanted to practice it were either burned or killed as witches and sorcerers. In India, for various reasons, it fell into the hands of persons who destroyed ninety per cent of the knowledge,
