The annual diagram is a valuable astrological forecasting technique that uses the 45-degree graphic ephemeris. At a glance it is easy to see all the aspects in effect for a given period of time, from a day to a year to several years to decades. Reinhold Ebertin takes the reader through a series of case studies in which the graphs are shown to be a powerful aid in determining the nature of events. In many instances the cases used are ones in which events were in fact foretold by him prior to the event. Also, many of the cases are drawn from actual counseling situations so that the reader can see how the graphs can be used in practical work.
