When I use the term "reciprocal vibration," what do I mean? I mean the adaptation of the Personality or Lower Self, to the Ego, or Higher Self, the dominating of the Personality ray by the ray of the Ego and the combining of their tones. I mean the blending of the primary color of the Higher Self with the secondary hue of the Lower Self until beauty is achieved. At first, there is dissonance and discord, a clashing of the colors, and a fight between the Higher and the Lower. But as time progresses, and later with the aid of the Master, harmony of color and tone is produced (a synonymous matter), until eventually you will have the basic note of matter, the major third of the aligned Personality, the dominant fifth of the Ego, followed by the full chord of the Monad or Spirit.

It is the dominant we seek at adeptship, and earlier the perfected third of the Personality. During our various incarnations we strike and ring the changes on all the intervening notes, and sometimes our lives are major and sometimes minor, but always they tend to flexibility and greater beauty. In due time, each note fits into its chord, the chord of the Spirit; each chord forms part of a phrase, the phrase or group to which the chord belongs; and the phrase goes to the completion of one seventh of the whole. The entire seven sections, then, complete the sonata of this solar system,  - a part of the threefold masterpiece of the Logos or God, the Master-Musician. [5]
