We have heard it said that there are many kinds or types of yoga. This idea of a variety in yoga arises on account of a sectional thinking, into which we perforce have introduced ourselves as the result of our mental structure. Really, the Yogas are not many, just as we cannot say that the rays of the sun are many, though they appear to be so due to a peculiar projectional structure of the mechanism of this emanation.

We have observed that there is an objective way of thinking and also a subjective way, the connection between which is what we call knowledge, or perception. Our knowledge of the world, or the knowledge of anything, is a reaction set up between the subject and the object. Unless these two are there in juxtaposition, there will not be knowledge; there will not be any kind of experience. Every experience is a reaction between the percipient subject and the perceived object, whatever be the nature of that object, physical or otherwise.

Now, we can think in three ways and so there are supposed to be three Yogas, the well-known systems of karma (action), bhakti (devotion) and jnana (knowledge), in which schools like that of kundalini yoga, tantra yoga, japa yoga, and even Patanjali's system of yoga, and various methods of self-analysis, get subsumed.

We have to recall to our memories that when we go deep into ourselves, we find the very same things that we discover when we go deep into anything outside. That which is deeply within us is also deeply within everything in the world. Even as, at the bottom of the crests of the ocean, we find the same base of the ocean, which is at the back of every other crest also, likewise, we will discover a common reality underlying every individuality. There is a substance which is equanimously present as the background of particulars, and yoga is the process of the gradual withdrawal of consciousness from particulars to the generals, until the highest common factor is reached. The particularised attention paid by consciousness in respect of any thing is to be withdrawn into the more general background of it, and the more it goes near to the general background, the more does it approximate to the ideal of yoga. This withdrawal, to repeat again what was noticed earlier, can be either inward, outward, or transcendent.

There are three kinds of withdrawal. But how is it possible to withdraw oneself in three ways? We are generally accustomed to the idea that withdrawal means going into one's own self in an individual sense, but it need not necessarily mean that. One can withdraw oneself even into an object by a peculiar adjustment of consciousness and in that technique of objective withdrawal, the object ceases to be an object any more. Here consciousness assumes a different position by an adjustment of itself with the object in a novel way. In fact, yoga is a gradual attempt of consciousness to convert every object into a subject; and the more do we succeed in transforming the object into the subject, the more are we said to be advancing in yoga.

The greatest problem in life is involvement in objectivity, externality, the conditioned attitude of the mind by which it segregates itself from all things which it thinks, or visualises. The world of objects is a connected whole; this is the doctrine of yoga. The world is not constituted of isolated parts as it appears to the outward senses of perception. The recognition of this inward connectedness of things in the form of the universe is the endeavour of yoga. Inasmuch as we are accustomed to think only in terms of objects and we cannot think in any other manner, we have to take the stand of the object first, and that method is the way of karma yoga and bhakti yoga, and partly of the yoga of Patanjali, and the initial stages of even jnana yoga. Everything starts with the concept of the object; only the notion of the object varies according to the different systems of practice, the notion getting widened gradually, in an ascending degree.

Before we start seriously any kind of practice in the direction of yoga, we must be well up with the requisite preparations. The achievements in yoga are a gradual evolution, a systematic advance and not a sudden jump. It is not a revolution that we are setting up. There is no revolutionary process in Nature. Everything grows slowly, stage by stage, without missing even one link in the process of development, as we have grown from babyhood to the adult stage. How beautifully does a tree grow from the seed! How many years does it take? There is no abrupt skipping from the seed to the fruit.

So is yoga a gradual developmental process of the 'wholeness' of our personality towards an achievement of All-Being. We have, therefore, to be cautious that the necessary preparations are made. We cannot suddenly conceive of the goal without being aware of the preparatory stages. Apart from the techniques to which we shall refer a little later, five of the requisites may be noted with advantage among many others: 1. Place, 2. Time, 3. Method, 4. Regularity, and 5. Whole-souled devotion to the Ideal.

You must have a place which is suited to the practice. You must also have a time chosen for the practice. You should have a method which has to be adopted continuously, without changing it every now and then. Then the practice must be regular and there should be no break in it. And, lastly which is perhaps the most important aspect of it, you must have a whole-souled love for the practice. It is said in the yoga scriptures that one loves yoga as the mother loves the child and thinks of it the whole day and night, and there is no other thought in the mind except that. "How shall I get it?" This ardent longing from the heart is itself half of the success in the practice, and everything else comes afterwards.

The co-operation from your deepest feelings is the affection that you have for yoga. You do not approach it with suspicions or doubts in the mind. It is absolutely certain that you are going to achieve the goal. This conviction should be there at all times. If the calculations are correct, the mathematical problem should yield the required result. You cannot doubt whether the calculations will give the result or not. The system of mathematics is so exact that there cannot be any suspicion about it.

Yoga is a highly technical and systematic subject, and if the methods adopted are correct, there should be no doubt, whatsoever, as to the possibility of the achievement of the end. The time that you take in reaching the goal depends upon the extent of the intensity of the practice and the emphasis that your feelings lay upon it, the extent to which you are in communion with the ideal which you are trying to contemplate.

We take into consideration, first of all, the place. Everyone knows what this actually means. One has to be located in a place which is conducive to the practice. Now, what do you mean by saying 'conducive to the practice'? There are certain necessities: geographical, climatic, social, political, physical and the like, which are associated with the selection of a place. Beautiful suggestions are given to us in such scriptures as the Svetasvatara Upanishad, for instance, as also in the Bhagavad Gita and the Yoga Vasishtha. The place should be pleasing to the inward sense of spiritual quest. You should be lifted up by the very atmosphere in which you are. That is why people go to sequestered places. The more are you away from centres which have an atmosphere of clash of personalities and egos, the more can you be in tune with Nature.

When you go for a walk, you go alone and not with another person. You will feel happier when you walk alone than when you go with another person; else, there would be two egos walking. And one ego never wholly agrees with another ego. You may be thick friends, but notwithstanding it, you are still two persons and not one person. The very fact that you are two persons shows that there are two egos and one has to adjust oneself in an artificial manner to the presence of the other. You cannot be natural when you are in the presence of another person. You cannot utter a word which will not be pleasing to the other. You cannot have a gesture made which is not to the taste of the other, and so on. But if you are under a tree you can do anything there, because the tree has no ego like the human being. The birds, the animals, have no egos like men and they do not bother about what you do, what you say, what you think, etc. Choose a place which is free from tensions arising from the presence of egos. This is the reason why we go to monasteries, temples, convents, and such other sanctified localities. Also it is said that elevated places are more convenient than others, because of the electro-magnetic influences which high altitudes are supposed to produce. The tops of mountains are regarded as very conducive. Places which are near vast areas of water, or near the ocean, are electro-magnetically more suggestive. This is the discovery of ancient sages. There is also a discovery that cloudy weather is more conducive to meditation than clear sky because of the presence of electric forces that are generated in the sky during the movement of clouds. These are minor matters, not very important things, but they are things to be remembered, as they are helpful.

Times which are suggestive of an automatic withdrawal of the mind from external activities are to be preferred. Night time is generally, and obviously, helpful because of an automatic tendency of the mind at that time to withdraw itself into subjectivity. When we speak of time for the practice of yoga, or meditation, what we actually mean is not merely the hour of the day, such as eight o'clock, etc., but a fixed time. There is a cyclic movement of everything in Nature. This system of cyclic movement applies not only to the external world of astronomy but also to the internal world of the psyche. If we start taking our meal at a particular hour and we continue taking it at the same hour, we will start feeling hungry at the same time and not at other times, because of a cyclic effect in Nature which generally gets associated with the way of thinking, and affects sympathetically the physiological functions.

Hence it is necessary that one should fix a specific time for contemplation, studies, etc., whatever the nature of the practice - not that one starts meditating today in the morning and tomorrow in the evening and the day after at midnight, etc. Such anomalies will create a kind of jarring effect and not yield a harmonious contribution to the practice. The time should be fixed, whatever the chosen hour be. There are some people who are anxious to get up very early in the morning. They force themselves into waking up into a consciousness of meditation imagined at a particular time which is suggested by scriptures, etc. This may not have the desired result following. No kind of force should be exerted upon the mind. It may be that early morning is good for certain reasons, but in the beginning one will not be able to adjust oneself to that hour, because one is not used to that life. It is better to take things easily as an art and not as a sort of labour or an imposition that has been inflicted upon the mind. Joy should be the touchstone of the practice and not uneasiness, pain or regret.

Yoga is a process of rejoicing. It is not a suffering. It is a movement through happiness. From one state of joy, we move to another state of joy. It is not that yoga starts with sorrow, or that it is a kind of prison-house into which we are thrown. We have sometimes a feeling that yoga is a torture, a suffering, to the normal life of man. Sadhana means a fear, and indicates an unnatural seriousness. This is so, often because people have created a picture of awe and sternness about yoga, an other-worldliness about it, dissociated from the natural likings of the human being. Our desires are, no doubt, obstacles to yoga. But they are 'our' desires; this much we must remember, and they are not somebody's. So, we have to wean ourselves from these desires gradually and not make it appear that we are peeling our own skin. Such a drastic step should not be taken, and it is not the intention of yoga.
