There are two great forces in the universe, silence and speech. Silence prepares, speech creates. Silence acts, speech gives the impulse to action. Silence compels, speech persuades. The immense and inscrutable processes of the world all perfect themselves within, in a deep and august silence, covered by a noisy and misleading surface of sound–the stir of innumerable waves above, the fathomless resistless mass of the ocean’s waters below. Men see the waves, they hear the rumour and the thousand voices and by these they judge the course of the future and the heart of God’s intention; but in nine cases out of ten they misjudge. Therefore it is said that in History it is always the unexpected that happens. But it would not be the unexpected if men could turn their eyes from superficies and look into substance, if they accustomed themselves to put aside appearances and penetrate beyond them to the secret and disguised reality, if they ceased listening to the noise of life and listened rather to its silence.

The greatest exertions are made with the breath held in; the faster the breathing, the more the dissipation of energy. He who in action can cease from breathing,–naturally, spontaneously,–is the master of Prana, the energy that acts and creates throughout the universe. It is a common experience of the Yogin that when thought ceases, breathing ceases,–the entire kumbhak effected by the Hathayogin with infinite trouble and gigantic effort, establishes itself easily and happily,–but when thought begins again, the breath resumes its activity. But when the thought flows without the resumption of the inbreathing and outbreathing, then the Prana is truly conquered. This is a law of Nature. When we strive to act, the forces of Nature do their will with us; when we grow still, we become their master. But there are two kinds of stillness–the helpless stillness of inertia, which heralds dissolution, and the stillness of assured sovereignty which commands the harmony of life. It is the sovereign stillness which is the calm of the Yogin. The more complete the calm, the mightier the yogic power, the greater the force in action. In this calm, right knowledge comes.
