One of the most powerful aids that yogic discipline can provide to the sportsman is to teach him how to renew his energies by drawing them from the inexhaustible source of universal energy.
Modern science has made great progress in the art of nourishment, which is the best known means of replenishing one’s energies. But this process is at best precarious and subject to all kinds of limitations. We shall not speak about it here, for the subject has already been discussed at great length. But it is quite obvious that so long as the world and men are what they are, food is an indispensable factor. Yogic science knows of other ways of acquiring energy, and we shall mention two of the most important.
The first is to put oneself in relation with the energies accumulated in the terrestrial material world and to draw freely from this inexhaustible source. These material energies are obscure and half unconscious; they encourage animality in man, but, at the same time, they establish a kind of harmonious relationship between the human being and material Nature. Those who know how to receive and use these energies are usually successful in life and succeed in everything they undertake. But they are still largely dependent on their living conditions and their state of bodily health. The harmony created in them is not immune from all attack; it usually vanishes when circumstances become adverse. The child spontaneously receives this energy from material Nature as he expends all his energies without calculating, joyfully and freely. But in most human beings, as they grow up, this faculty is blunted by the worries of life, as a result of the predominant place which mental activities come to occupy in the consciousness.
However, there is a source of energy which, once discovered, is never exhausted, whatever the outer circumstances and physical conditions of life may be. It is the energy that can be described as spiritual, and is received no longer from below, from the inconscient depths, but from above, from the supreme origin of the universe and man, from the all-powerful and eternal splendours of the superconscient. It is there, all around us, permeating everything; and to enter into contact with it and to receive it, it is enough to aspire sincerely for it, to open oneself to it in faith and trust, to widen one’s consciousness and identify it with the universal Consciousness.
At the outset, this may seem very difficult, if not impossible. Yet by examining this phenomenon more closely, one can see that it is not so alien, not so remote from the normally developed human consciousness. Indeed, there are very few people who have not felt, at least once in their lives, as if lifted up beyond themselves, filled with an unexpected and uncommon force which, for a time, has made them capable of doing anything whatever; at such moments nothing seems too difficult and the word “impossible” loses its meaning.
This experience, however fleeting it may be, gives a glimpse of the kind of contact with the higher energy that yogic discipline can secure and maintain.
The method of achieving this contact can hardly be given here. Besides, it is something individual and unique for each one, which starts from where he stands, adapting itself to his personal needs and helping him to take one more step forward. The path is sometimes long and slow, but the result is worth the trouble one takes. We can easily imagine the consequences of this power to draw at will and in all circumstances on the boundless source of an energy that is all-powerful in its luminous purity. Weariness, exhaustion, illness, old age and even death become mere obstacles on the way, which a persistent will is sure to overcome.
Bulletin, August 1949 
Are you conscious of the energies you receive and those you spend?
One is more or less conscious of the energy one spends, especially when one wastes it too much! It is a question here of the constant exchange between receiving and spending! Before the age of reason, little children receive a lot of energy and they spend it lavishly, without thinking, and this allows them to play for hours together without getting tired. But gradually, as thought develops, one begins to measure and calculate the energy spent—usually this is futile, for unless you have the knowledge of the process of receiving energy, it is better to spend freely what you get than let it stagnate within you.
First, you must become conscious of the receiving of energies, their passing into your being and their expenditure. Next, you must have a sort of higher instinct which tells you whence the most favourable energies come; then you put yourself in contact with them through thought, through stillness or any other process—there are many. You must know what energy you want, whence it comes, of what it is composed. Later comes the control of the energy received. Ninety percent of men do not absorb enough energy or they take in too much and do not assimilate what they take—as soon as they have had a sufficient dose they immediately throw it out by becoming restless, talking, shouting, You must know how to keep within you the received energy and concentrate it fully on the desired activity and not on anything else. If you can do this, you won’t need to use your will. You need only gather together all the energies received and use them consciously, concentrate with the maximum attention in order to do everything you want.
And you must know how to give a real value to what you want to do—what the higher part of your being wants to do—for to do what one likes to do is not difficult. 
When we play badly we find that we have no energy, but if we play well, with great enthusiasm, we find that energy comes. Why?
This is perfectly true. To enter into contact with terrestrial energy, one must establish a certain harmony within oneself. If you know the game well, if you know how to make the moves and if you take an enthusiastic interest, if you have a sort of ambition (quite childish perhaps), a desire to win, then as you go on succeeding you feel a kind of inner joy, not perhaps very profound, but creating the harmony necessary for the interchange of energy. On the other hand, those who do not know how to accept defeat, who get angry and bad-tempered when things do not go according to their wish, lose their energy more and more.
Also, if you slip into depression, you cut every source of energy—from above, from below, from everywhere. That is the best way of falling into inertia. You must absolutely refuse to be depressed.
Depression is always the sign of an acute egoism. When you feel that it is coming near, tell yourself: “I am in a state of egoistic illness, I must cure myself of it.” 
How is it that as mental activities increase, the capacity to renew one’s energies diminishes?
In adults mental activity tends to paralyse the spontaneous movement of exchange of energies. Till he is fourteen, every child, apart from a few rare exceptions, is a little animal; he renews his energies spontaneously like an animal by means of the same activities and exchanges. But the mind introduces a disequilibrium in the being; spontaneous action is replaced by something that wants to know, to regulate, to decide, etc., and to get back this capacity to renew spontaneously one’s energies, one must rise to a higher rung above the instincts, that is, from ordinary mental activity one must pass directly into intuition.
“Yet there is a source of energy which, once discovered, never dries up, whatever the circumstances and the physical conditions in life. It is the energy that can be described as spiritual, that which is received not from below, from the depths of inconscience, but from above, from the supreme origin of men and the universe, from the all-powerful and eternal splendours of the superconscious. It is there, everywhere around us, penetrating everything and to enter into contact with it and receive it, it is sufficient to sincerely aspire for it, to open oneself to it in faith and confidence so as to enlarge one’s consciousness for identifying it with the universal Consciousness.”

In these articles I am trying to put into ordinary terms the whole yogic terminology, for these Bulletins are meant more for people who lead an ordinary life, though also for students of yoga—I mean people who are primarily interested in a purely physical material life but who try to attain more perfection in their physical life than is usual in ordinary conditions. It is a very difficult task but it is a kind of yoga. These people call themselves “materialists” and they are apt to get agitated or irritated if yogic terms are used, so one must speak their language avoiding terms likely to shock them. But I have known in my life persons who called themselves “materialists” and yet followed a much severer discipline than those who claim to do yoga.
What we want is that humanity should progress; whether it professes to lead a yogic life or not matters little, provided it makes the necessary effort for progress.
