This new, most comprehensive description of the transits through our planetary system is the most inclusive treatment ever written, culminating more than 50 years of astrological research by the renowned astrologer and author Robert Hand. This work expands and supplements what has been provided in previous transit references. New material includes transits by and to Chiron, transits to the lunar nodes, and all transits by semisquare, sesquiquadrate, semisextile, and quincunx (except for the lunar nodes). The interpretive passages on the individual transits now include separate passages on the “Principles and Inward Effects” of each transit, plus indications of what each transit is best used for, and where they may present challenges. In addition, there is extensive new introductory material for each transiting body as well as a section that introduces the theory of transits, a philosophy of transits (why some are more difficult than others), various methods for applying them to a natal chart, and graphic techniques that have been made more useful since the advent of personal computers.
