This is the law of the first plane, and it governs all the atomic subplanes of each plane. It marks the beginning of the work of the Logos, the first setting in motion of mulaprakriti. On each plane the vibration of the atomic subplane sets in motion the matter of that plane. It is the key measure. We might sum up the significance of this law in the words, "light" or "fire." It is the law of fire; it governs the transmutation of differentiated colors back to their synthesis. It controls the breaking up of the One into the seven, and then the reabsorption back into the One. It is really the basic law of evolution, which necessitates involution. It is analogous to the first movement the Logos made to express Himself through this solar system. He uttered the Sound, a threefold Sound, one sound for each of His three systems, and started a ripple on the ocean of space. The Sound grows in volume as time progresses, and when it has reached its full volume, when it is fully completed, it forms one of the notes in the major cosmic chord. Each note has six subtones, which, with the first, make the seven; the Law of Vibration, therefore, comprises eighteen lesser vibrations and three major, making the twenty-one of our three systems. Two multiplied by nine (2x9), makes the necessary eighteen, which is the key number of our love system. Twenty-seven holds hid the mystery of the third system.

On the path of evolution this law controls the positive aspect of the process. All is rhythm and movement, and when all that evolves on each plane attains the vibration of the atomic subplane, then the goal is reached. When, therefore, we have achieved the first main vibrations, and have perfected vehicles for all evolutions (not merely the human), of fivefold atomic subplane matter, then we have completed the round of evolution for this system. In the coming system we shall add the next two vibrations that complete the scale, and our Logos will then have completed His building.

The fourth Creative Hierarchy, that of the human Monads, has to learn to vibrate positively, but the devas proceed along the. line of least resistance; they remain negative, taking the line of acquiescence, of falling in with the law. Only the human Monads, and only in the three worlds, follow the positive line, and by resistance, struggle, battle and strife learn the lesson of divine acquiescence. Yet, owing to the increase of friction through that very struggle, they progress with a relatively greater rapidity than the devas. They have need to do this, for they have lost ground to make up.
