Book excerpt: 1. The first is like the nightingale’s sweet voice chanting a song of parting to its mate. 2. The second comes as the sound of a silver cymbal of the Dhyanis, awakening the twinkling stars. Our body is an Aeolian harp chorded with two sets of strings: one made of pure silver, the other of catgut. 3. The next is as the plaint melodious of the ocean-sprite imprisoned in its shell. It is the Voice of Divine Wisdom and last word of the Secret Doctrine. 4. And this is followed by the chant of Vina, attuning fellow disciples to the harmonies of Wisdom. Even the memory of the sleeper is like the seven-stringed Aeolian harp, his mind sweeping over the chords. 5. The fifth like sound of bamboo-flute shrills in thine ear, bestowing knowledge of the awful mysteries and priceless secrets of initiation. 6. It changes next into a trumpet-blast, beckoning the Dragon of Esoteric Wisdom to come out of Darkness. 7. The last vibrates like the dull rumbling of a thunder-cloud. When the six are slain and at the Master’s feet are laid, then is the pupil merged into the One, becomes that One, and lives therein. The seventh swallows all the other sounds: they die, and then are heard no more. The two Opposing Forces are finally harmonised. The freed Spirit rises to its former glory. The Great Serpent uncoils. Only Sat remains. The Higher Self is swallowed up by the Great Serpent; the lower, disappears forever.
