Esoteric astrology seeks to incorporate the personality within a broader contextual framework linking the personality with the soul. The field of esoteric astrology has developed through the contributions of H. P. Blavatsky (founder of the Theosophical Society), Tibetan Master Dhjwal Kuhl (DK) with Alice A. Bailey (co-founder of Lucis Trust), Rudolf Steiner, Alan Leo, and E. H. Bailey. Interpretations in esoteric astrology are based upon full knowledge of the seven creative rays of energy emanating from the Big Dipper. Esoteric astrology, as written in the Bailey texts, is a preparation and explanation for Soul infusion. In Esoteric Astrology, the rising sign of the horoscope sets the keynote for the soul's purpose with the esoteric ruler of the rising sign showing how and where the soul's purpose works out.
