The middle rays of the solar spectrum—blue, green, and yellow—give a very powerful triangle, a wonderful working triangle of forces; for green is Hermetic silver, yellow is Hermetic gold, and blue is a despatch-messenger from the “Lord of the Worlds,” Jupiter.
The blue and the yellow of this group, on account of their position—the third and the fifth reckoned both ways—have been chosen as the colours of our incense-holders, alternating on the points of the Pentacle. As odours are also correlated with colours, and as sandal-wood is the perfume which belongs to the sun, we use that incense to intensify the vibrations from the radiating points, in order to increase the volume of accord which will reach other centres at a distance; for the akasa is more sensitive than an Eolian harp—it registers the very aroma[aroma] of our thoughts. It was, therefore, no exaggeration of the poet when he said:
“Guard well thy thought:
Our thoughts are heard in Heaven.”
But if colours and sounds are spiritual numerals, then the seven symbolical points of the Pentacle represent numbers of the greatest importance in world-building, and in soul-building also. For we must all build our own souls. And the symbology of the interlacing of the triangle of spirit with the triangle of matter, finds its correspondence in man, the little world, who, though a spiritual ego, yet dwells in a physical house, and whose business it is to merge himself completely into the region of the white triangle.
When Man has raised his vibrations into perfect harmony with the universal sun, he has then unbound himself from the wheel of re-birth—the Zodiac—and is ready to enter Nirvana.
The word “heaven” in Hebrew signifies the abode of the sun. When, therefore, the Nazarene said “The Kingdom of Heaven is within you,” he virtually declared that all the seven cosmic powers are resident within us.
Esoteric science recognises man as a septenary, working in conjunction with other orders of numerals which register divine vibrations.
All nature listens to that universal song, and the music of the spheres is no fable. The swarming zöospores in the protoplasm of plants hear it, and thrilled by that enchantment, fall into invisible rhythm, bringing up by quick marches into the region of Day the tiny dwellers in stem and leaf. How do we know that the mystery of the six-sided cell of the honey-bee may not find its solution here? Perhaps the bee is susceptible only to vibrations which fall into these lines, and faithfully obeys the master-musician in the construction of its hexagonal house. The great law of cosmic and microcosmic correspondence was revealed ages ago to the Sages who listened, and listening, heard the wondrous revelations breathed forth from the harp of Akasa. Sighing winds from other worlds passed over the delicate strings, and as they passed, uttered in soundless tones the profound mystery of near and remote planets. These Sages dwelt in that White Palace—the Lotus of the Heart—the sun-palace indeed. From centre to circumference their vast circle of vision was permeated by the reflected All, and from the White Palace they ascended the sacred mountain Meru, where dwelleth wisdom and love.
The key which opens the White Palace is held by the seven mystic children of the Royal Arch of the Rainbow, guarding the seven gates of the Sun, every gate of which answers to a musical note, and every note of which enfolds three tones.
