This lecture covers the use of the Astrological 90 degree dial along with midpoints and is based on Laura's book, "Time Passages" and her new report writer with Matrix Software called Midpoint Keys. Laura will discuss the historical value of midpoints, as well as their spiritual, psychological and physical manifestations. She will also use timing of midpoint structures and show how this system is used for accurate event timing of past and future events. Laura will also discuss how each midpoint has a medical implication and how to avoid the shadow side of the energy. This is a very dynamic lecture and Laura will use charts from guests in the audience to demonstrate personal timing of critical events in one's life though the use of their personal midpoints.
