Reinhold Ebertin, one of the most respected astrologers of the 20th century, presents a clear explanation on how to interpret the daily motion of the planets. Special attention is given to the favorable and unfavorable potential of each aspect to the natal planets. Ebertin also explores the cosmogram, clearly defines transits and their evaluation, and discusses parallels. A chapter is devoted to each planet and Moon's Node, as well as another which focuses on the significance of the Midheaven and Ascendant.
