The invisible Force producing tangible results both inward and outward is the whole meaning of the Yogic consciousness. Your question about Yoga bringing merely a feeling of Power without any result was really very strange. Who would be satisfied with such a meaningless hallucination and call it Power? If we had not had thousands of experiences showing that the Power within could alter the mind, develop its powers, add new ones, bring in new ranges of knowledge, master the vital movements, change the character, influence men and things, control the conditions and functionings of the body, work as a concrete dynamic Force on other forces, modify events, etc., etc., we would not speak of it as we do. Moreover, it is not only in its results but in its movements that the Force is tangible and concrete. When I speak of feeling Force of Power, I do not mean simply having a vague sense of it, but feeling it concretely and consequently being able to direct it, manipulate it, watch its movement, be conscious of its mass and intensity and in the same way of that of other, perhaps opposing forces; all these things are possible and usual by the development of Yoga.
It is not, unless it is supramental Force, a Power that acts without conditions and limits. The conditions and limits under which Yoga or Sadhana has to be worked out are not arbitrary or capricious; they arise from the nature of things. These including the will, receptivity, assent, self-opening and surrender of the Sadhak have to be respected by the Yoga-force, unless it receives a sanction from the Supreme to override everything and get something done, but that sanction is sparingly given. It is only if the supramental Power came fully down, not merely sent its influences through the Overmind, that things could be very radically directed towards that object — for then the sanction would not be rare. For the Law of the Truth would be at work, not constantly balanced by the law of the Ignorance.
Still the Yoga-force is always tangible and concrete in the way I have described and has tangible results. But it is invisible — not like a blow given or the rush of a motor car knocking somebody down which the physical senses can at once perceive. How is the mere physical mind to know that it is there and working? By its results? But how can it know that the results were that of the Yogic force and not of something else? One of two things it must be. Either it must allow the consciousness to go inside, to become aware of inner things, to believe in the experience of the invisible and the supraphysical, and then by experience, by the opening of new capacities, it becomes conscious of these forces and can see, follow and use their workings, just as the Scientist uses the unseen forces of Nature. Or one must have faith and watch and open oneself and then it will begin to see how things happen, it will notice that when the Force was called in, there began after a time to be a result, then repetitions, more repetitions, more clear andtangible results, increasing frequency, increasing consistency of results, a feeling and awareness of the Force at work — until the experience becomes daily, regular, normal, complete. These are the two main methods, one internal, working from in outward, the other external, working from outside and calling the inner force out till it penetrates and is visible in the exterior consciousness. But neither can be done if one insists always on the extrovert attitude, the external concrete only and refuses to join to it the internal concrete — or if the physical mind at every step raises a dance of doubts which refuses to allow the nascent experience to develop. Even the Scientist carrying on a new experiment would never succeed if he allowed his mind to behave in that way.
