A grand trine pattern is formed by three planets positioned approximately 120 degrees apart around the circle. This is an aspect of ease and flow, conceptual and interpretive ability; of service, and sensitivity to the senses rather than sensuality. It denotes the ability to feel compassion. Can be apathetic and indifferent to responsibilities if there are not enough challenging aspects in the pattern.
A minor grand trine is a trine with a planet at the midpoint, making a sextile to each end of the trine. It is an easy flow and natural ability, much as the grand trine. It may be of lesser strength, depending upon which planets are involved and their overall ‘weight’ in the chart. So the sun, moon or chart ruler [ruler of the ascendant] would make it much more powerful and significant.
The mystic trine is another quite similar pattern, where a trine is divided by a planet making a quintile to one planet of the trine and a septile to the other. This is an exceptionally fortunate pattern, because the natural ease of the trine is enhanced with the remarkable creativity and talent of the quintile, and charged with the sense of destiny or divine purpose implied by the septile. There is an indication of great potential for creativity, growth and accomplishment within this pattern.
The grand cross, four planets positioned 90 degrees apart around the circle, is a rare and powerful pattern. It is the most rooted and stable of patterns, giving great sensual, practical, and psychic intuition. Potentially a stable structure around which the universe revolves. It can be a source of strength and stability, but also may tend to be self-defeating because of the urge to go in several directions at once, thereby going nowhere.
The wedge is two planets opposed, with another forming a 60/120 degree aspect to the opposition. A pattern of mental work and service, given more to sensitivity than sensuality. Receptivity and awareness of others and of one’s surroundings is indicated. Willing to serve, verbal and social.
The yod is formed by two [or more] planets in sextile [60 degrees] to each other, each forming a quincunx [150 degrees] to a third planet. It is sometimes called the 'Finger of Fate’, or the 'Finger of God’, and its meaning has to do with destiny. It creates a continuous need for adjustment with relation to the planet that is in quincunx to the other two, or to which the 'finger’ is pointing.
A T-square is two planets in opposition, with a third at right angles to both. A powerful pattern on the physical, sensual, and psychic levels. Indicates the ability to sense, intuit, and know things. A strong incarnation, rooted in the practical and the social. May experience cycles of crisis involving the “squared” planet.
A grand sextile is a pattern which includes six connected sextiles, in other words, forms a symmetrical hexagon. This is a very auspicious pattern, a life of great ease and opportunity, but there is danger of a lack of motivation due to not enough challenge in the life. Potentially very creative, there is virtually nothing this person can’t manifest with ease. Extremely gifted.
Mystic rectangle is four planets set 60/120/60/120 apart. A classic pattern pointing to verbal and mental abilities. Sensitive and service-oriented. Sometimes indicates mental syndromes visible to others but hard for the person with the pattern to solve.
