By seeing the colors we may see how far it reaches without. It reaches so far that if we are in a large room two hundred yards long, it will reach the whole length of the room. Or if we look into the sky, we may see the colors there, showing that it is only there that the breath has room enough to extend. There is no aim that cannot be accomplished by the breath, and if we fail to accomplish our aims it is because we have a thousand different aims before us, not one alone. It becomes very difficult in the world where attacks come from a thousand sides. The breath goes out to meet an attack from one side, and instantly it has to turn to another side to face another attack. It would have to turn to every side in the same moment, and this it cannot do. This is the reason of the failure even of the sages and saints and mystics.
