The Yoga Sutras of Patanjali
BOOK III

These are extreme illustrations; but with all knowledge the order of perception is the same: first, the excitation of the mind by the new object impressed on it; then the control of the mind from within; upon which follows the perception of the nature of the object. Where the eyes of the spiritual man are open, this will be a true and penetrating spiritual perception. In some such way do our living experiences come to us; first, with a shock of pain; then the Soul steadies itself and controls the pain; then the spirit perceives the lesson of the event, and its bearing upon the progressive revelation of life.

10. Through frequent repetition of this process, the mind becomes habituated to it, and there arises an equable flow of perceiving consciousness.

Control of the mind by the Soul, like control of the muscles by the mind, comes by practice, and constant voluntary repetition.

As an example of control of the muscles by the mind, take the ceaseless practice by which a musician gains mastery over his instrument, or a fencer gains skill with a rapier. Innumerable small efforts of attention will make a result which seems well-nigh miraculous; which, for the novice, is really miraculous. Then consider that far more wonderful instrument, the perceiving mind, played on by that fine musician, the Soul. Here again, innumerable small efforts of attention will accumulate into mastery, and a mastery worth winning. For a concrete example, take the gradual conquest of each day, the effort to live that day for the Soul. To him that is faithful unto death, the Master gives the crown of life.

11. The gradual conquest of the mind's tendency to flit from one object to another, and the power of one-pointedness, make the development of Contemplation.

As an illustration of the mind's tendency to flit from one object to another, take a small boy, learning arithmetic. He begins: two ones are two; three ones are three-and then he thinks of three coins in his pocket, which will purchase so much candy, in the store down the street, next to the toy-shop, where are base-balls, marbles and so on,--and then he comes back with a jerk, to four ones are four. So with us also. We are seeking the meaning of our task, but the mind takes advantage of a moment of slackened attention, and flits off from one frivolous detail to another, till we suddenly come back to consciousness after traversing leagues of space. We must learn to conquer this, and to go back within ourselves into the beam of perceiving consciousness itself, which is a beam of the Oversoul. This is the true one-pointedness, the bringing of our consciousness to a focus in the Soul.

12. When, following this, the controlled manifold tendency and the aroused one-pointedness are equally balanced parts of the perceiving consciousness, his the development of one-pointedness.
