As was said at the outset, each consciousness is related to all consciousness; and, through it, has a potential consciousness of all things; whether subtle or concealed or obscure. An understanding of this great truth will come with practice. As one of the wise has said, we have no conception of the power of Meditation. 26. By perfectly concentrated Meditation on the sun comes a knowledge of the worlds. This has several meanings: First, by a knowledge of the constitution of the sun, astronomers can understand the kindred nature of the stars. And it is said that there is a finer astronomy, where the spiritual man is the astronomer. But the sun also means the Soul, and through knowledge of the Soul comes a knowledge of the realms of life. 27. By perfectly concentrated Meditation on the moon comes a knowledge of the lunar mansions. Here again are different meanings. The moon is, first, the companion planet, which, each day, passes backward through one mansion of the stars. By watching the moon, the boundaries of the mansion are learned, with their succession in the great time-dial of the sky. But the moon also symbolizes the analytic mind, with its divided realms; and these, too, may be understood through perfectly concentrated Meditation. 28. By perfectly concentrated Meditation on the fixed pole-star comes a knowledge of the motions of the stars. Addressing Duty, stern daughter of the Voice of God, Wordsworth finely said: Thou cost preserve the stars from wrong, And the most ancient heavens through thee are fresh and strong— thus suggesting a profound relation between the moral powers and the powers that rule the worlds. So in this Sutra the fixed polestar is the eternal spirit about which all things move, as well as the star toward which points the axis of the earth. Deep mysteries attend both, and the veil of mystery is only to be raised by Meditation, by open-eyed vision of the awakened spiritual man. 29. Perfectly concentrated Meditation on the centre of force in the lower trunk brings an understanding of the order of the bodily powers.
