The Yod is an aspect pattern that has been widely discussed as a challenging pattern, emotionally and psychologically, presenting problems that are difficult to solve. The two quincunxes involved in a Yod pattern, depending on the planets involved, are either waxing or waning, and are very different in nature: Virgo or Scorpio archetypes.
As an astrologer being interested in giving practical advice to my clients, I will examine how Yod Bearers are in constant need of something that probes the mind, or in search of an application of a skill. They may possess a special skill in solving problems, or have a capacity to "see" things that others don’t. Once they become conscious of that and apply it in a particular realm of life, it may serve as a very rewarding release of the inherent tension of the pattern. Mercury, Mars (and Pluto) would be planets to examine as hidden players, even if they do not feature in the pattern.
