Simplified scientific astrology : a complete textbook on the art of erecting a horoscope, with philosophic encyclopedia and tables of planetary hours

Max Heindel’s textbook presents astrology as an orderly, learnable system and emphasizes the construction and interpretation of the horoscope. Historically notable for its place in early twentieth-century esoteric astrology, it contains instructional material, reference tables, and a broader philosophical framework linking astrology to spiritual ideas.

Max Heindel (1865–1919) was a Danish-American mystic and writer who founded the Rosicrucian Fellowship. His major work, The Rosicrucian Cosmo-Conception, presented a synthesis of esoteric Christianity, occult cosmology, and spiritual development that became influential in modern Western esotericism.
