What is the significance of Draco?

This essay examines the esoteric significance of the constellation Draco, its relation to this solar system, Earth and its importance in ancient cultures. The symbolism of dragons and serpents exists in most religious and mythological traditions – as expressions of wisdom or materiality. Draco the Dragon has for countless cycles been host to the pole-star Thuban, imparting certain energies essential for the hastening of human evolution on planet Earth. Further exploration opens up a large range of relationships to other constellations such as Capricorn or Ursa Minor, various planets, long term cycles, rootraces and the planetary centre known as Shamballa. The author’s two main source references are from the writings of H.P. Blavatsky and Alice A. Bailey.

How has the Earth wheel evolved?

Hence, the evolution of our even “tinier” Earth wheel has been hastened through history by the direct invocation of the forces of Draco – through astronomical alignment with the monuments and temples of our most advanced civilisations. Those edifices have all been aligned with the solstices, equinoxes and pole stars above whilst below, these buildings have been positioned upon magnetic ley lines upon the Earth surface; many have incorporated in them the most extraordinary sacred geometry to facilitate the alignment of the heavens with earth; invoking celestial guidance into the sacred sanctuaries by the priest-initiates, astronomer-astrologers, the intermediaries between the Solar Logos and a civilisation. Understanding the aforementioned Fifth Creative Hierarchy, ruled by Capricorn-Makara is most important, particularly through the study of some of its greatest exponents such as the Buddha – often depicted under a multi- headed cobra: “The seven-headed serpent Anantaof Vishnu, the Nagaround Buddha — the great dragon eternity biting with its activehead its passivetail, from the emanations of which spring worlds, beings and things.

In days of old—of the divine Dynastieson Earth—the now dreaded Reptile was regarded as the first beam of light that radiated from the abyss of divine Mystery. Various were the forms which it was made to assume, and numerous the natural symbols adapted to it, as it crossed æons of Time: as from

The same consciousness guided construction in all these civilisations. Draco’s Connection with Neptune “A peculiar group of Beings connected with a certain constellation and the lesser Dragon, who have their habitat on Neptune and work with the sixth principle in the solar system. They take physical form, animated by purified desire, controlled by mind, and are the dispensers of love-wisdom by means of certain of the "Halls of Wisdom" on the various planets. The words "Halls of Wisdom" in their esoteric significance describe a stage of consciousness not a location.”33
