Here we approach a section of the teaching which has manifestly a two-fold meaning. The first is physical, and concerns the bodily position of the student, and the regulation of breathing. These things have their direct influence upon soul-life, the life of the spiritual man, since it is always and everywhere true that our study demands a sound mind in a sound body. The present sentence declares that, for work and for meditation, the position of the body must be steady and without strain, in order that the finer currents of life may run their course.
It applies further to the poise of the soul, that fine balance and stability which nothing can shake, where the consciousness rests on the firm foundation of spiritual being. This is indeed the house set upon a rock, which the winds and waves beat upon in vain.
47. Right poise is to be gained by steady and temperate effort, and by setting the heart upon the everlasting.
Here again, there is the two-fold meaning, for physical poise is to be gained by steady effort of the muscles, by gradual and wise training, linked with a right understanding of, and relation with, the universal force of gravity. Uprightness of body demands that both these conditions shall be fulfilled.
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.
