In like manner the firm and upright poise of the spiritual man is to be gained by steady and continued effort, always guided by wisdom, and by setting the heart on the Eternal, filling the soul with the atmosphere of the spiritual world. Neither is effective without the other. Aspiration without effort brings weakness; effort without aspiration brings a false strength, not resting on enduring things. The two together make for the right poise which sets the spiritual man firmly and steadfastly on his feet. 48. The fruit of right poise is the strength to resist the shocks of infatuation or sorrow. In the simpler physical sense, which is also coveted by the wording of the original, this sentence means that wise effort establishes such bodily poise that the accidents of life cannot disturb it, as the captain remains steady, though disaster overtake his ship. But the deeper sense is far more important. The spiritual man, too, must learn to withstand all shocks, to remain steadfast through the perturbations of external things and the storms and whirlwinds of the psychical world. This is the power which is gained by wise, continuous effort, and by filling the spirit with the atmosphere of the Eternal. 49. When this is gained, there follows the right guidance of the life-currents, the control of the incoming and outgoing breath. It is well understood to-day that most of our maladies come from impure conditions of the blood. It is coming to be understood that right breathing, right oxygenation, will do very much to keep the blood clean and pure. Therefore a right knowledge of breathing is a part of the science of life. But the deeper meaning is, that the spiritual man, when he has gained poise through right effort and aspiration, can stand firm, and guide the currents of his life, both the incoming current of events, and the outgoing current of his acts. Exactly the same symbolism is used in the saying: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man…. Those things which proceed out of the mouth come forth from the heart … out of the heart proceed evil thoughts, murders, uncleanness, thefts, false witness, blasphemies. Therefore the first step in purification is to keep the Commandments. 50. The life-current is either outward, or inward, or balanced; it is regulated according to place, time, number; it is prolonged and subtle. The technical, physical side of this has its value. In the breath, there should be right inbreathing, followed by the period of pause, when the air comes into contact with the blood, and this again followed by right outbreathing, even, steady, silent. Further, the lungs should be evenly filled; many maladies may arise from the neglect and consequent weakening of some region of the lungs. And the number of breaths is so important, so closely related to health, that every nurse’s chart records it.
