Astrological Practice, Astrological Chart Analysis, and Delineation. This archival document is an instructional reference guide titled “THOSE ELUSIVE LACKS” by Marion D. March. March examines how the absence of specific astrological components (elements, qualities, house emphasis, aspects, or active planetary placements) influences human behavior and psychological development. She explains that individuals naturally compensate or overcompensate for missing elements by using house placements or rising signs. The text details the specific behavioral consequences of lacking elemental groups (Fire, Earth, Air, Water), missing sign qualities (Cardinal, Fixed, Mutable), unoccupied house categories, unaspected planets, and missing major aspects such as squares, oppositions, and quincunxes, illustrating each concept with real-world chart examples of notable historical figures.
