Why is the violet flame the singing flame?

88.   Ignorance, preceptor of humanity, sees the planet as beginning and end; but reason indicates that such accepted formulae, confining cosmos within narrow boundaries, will bring on catastrophe.  Expecting an end, the human consciousness receives endless evidences of its karma and is perplexed over these calamities.        -M:  IIninity 1, 1930

475.  All spiritual constructions sound a spatial keynote.  Upon this keynote resound the subtle organisms.        -M:  Infinity 2, 1930

  Each ascended master has a musical keynote, a piece of music that keys into the causal body or Electronic Presence of the master.       -Messengers M & E Prophet:  Hilarion the Healer, 2004, p. 65

  Beloved ones, there is only one activity that can resolve the crisis of division of the races in America and throughout the Earth--and it is the violet flame, it is the action of the sacred fire, it is the teachings of the ascended masters....Why is the violet flame the singing flame?
Because it sings the tune of the keynote of the atom.  Whatever the substance--a tree, a flower, the mountains, the body temple, the soul--every atom and every molecule of Spirit and matter has its vibration, its keynote.  And when the violet flame touches that particle it automatically sings the note of that substance and that substance conforms to tits own inner blueprint, its own inner harmony, and the violet flame sings many many melodies all of the day.        -Saint Germain, in Messengers M & E Prophet:  Science of the Spoken Word, 1991, pp. 173 & 175
