We do not have to look about us very far or for very long to realize the disastrous effects produced on the inner life of man by this age of noise. Spun about in the whirl of business, enslaved to countless technical inventions, man is severed from God and from the world of the spirit. Non in commotione Deus: God does not dwell in turbulence. To find him, there must be calm within; certain senses must be hushed. Tossed around as we are, if God wishes to speak to us, his voice, small and still, will be lost in the hubbub of our daily lives; the rackets and noise drowning our minds will prevent his penetration into that seclusion we call “heart”–the living witness of that life in us which is most sacred and most true: the life we call “inner” or “spiritual.

Nowadays, to be sure, we are more “comprehensive.” In particular, we pay more attention to the body. It may even be that we go too far. On the other hand, are there not too many intellectuals about who, without knowing it, have put a muzzle on their hearts, and whose “spiritual life” misses those deep intuitions that are of the world of the spirit?All these people–the “brains,” the spiritualists, as well as those who are embarrassed or engrossed by the body–may be taught Yoga (I saw “may,” because they have to give themselves to it) that they cannot become truly themselves unless they accept their nature as men and aim at establishing balance between the parts of man in is; this nature of ours which is at one and the same time an animal body (corpus-anima), thinking soul (animus-mens) and spirit (spiritus-cor). It is a harmony among these “three” that is sought in each of us by the grace of redemption. Christ came in the first place so that this “creature of God” within us, concealed under a human complex, bruised and torn by original sin, should flower and open out in its full beauty and wealth of talent. Any ascetic discipline that works towards this works, in fact, hand in hand with grace, and that is why I have roundly stated that a Yoga that calms the senses, pacifies the soul, and frees certain intuitive or affective powers in us can be of inestimable service to the West. It can make people into true Christians, dynamic and open, by helping them to be men.

To get rid of a few problems in general health, to increase one's capacity for work, to make one's character gentler and stronger, to free oneself of various complexes, to create in oneself a whole atmosphere of calm and silence, and to do this by exercises in a gymnastic of repose and by a simple but careful method of breath-control - such aims may appear humble enough, rather down to earth, and a far cry form the goal of even the most modest of yogis. Yet I am certain that they will be able to work real miracles here in the West; to change lives and temperaments completely, making them healthier, more open; to increase their degree of engagement; and to render them more receptive to impulses and promptings from heaven.

By becoming clearly contemplative in a matter of weeks, my prayer had been given a particular and novel cast; and this was matched by the distinctness in the reprecussions my daily sessions of exercises were having on my everyday life, as well as on the many different occupations which a monk is vowed to carry out. The genuine sense of euphoria that followed the exercises persisted in me and transfigured my day. During the early months I had to face up to the sort of difficulties which put one's nerves to the test, and which would certainly have put me on my back before. As it was, everything went off so smoothly and I took it all so well that I trained everyone under my charge to develop the attitude of 'accepting rather than undergoing.
