Understanding a Grand Trine
If you have been researching your birth chart and realized you have an equilateral triangle, then what you are looking at is a grand trine. A trine is formed whenever two planets are three signs (or 120 degrees) apart. A grand trine, then, consists of three simultaneous trines, with each of the three planets 120 degrees away from the others.
Note the Planetary Involvement
A major factor to consider when you have a grand trine on your chart is which planets are involved. Astrologers believe that the symbolic archetypes of this power trio join forces when a grand trine is present. In a way, you can think of the grand trine as a frame that amplifies the power of what lies within it.
Next note the Element Involved
Exact grand trines are of 1 element, but grand trines can be different elements depending on how wide the orb. A fire grand trine represents active inspiration, bold creativity, enthusiasm, pride, and sometimes self-absorption. An earth grand trine represents worldly wisdom, an instinct for what’s needed for bountiful harvests, sensualism, and artistry. An air grand trine represents ambitious thinking and planning; intellectual curiosity; detachment and calm; and social engagement. A water grand trine represents a vivid inner life, strong feelings, intimacy, artistry, sentimentality, and a desire to reflect.
The strength of the trine aspect all depends very much on the state of the rest of the chart and also the planets involved in a grand trine. While many believe having a Grand Trine in your natal chart lends you to luck in life, it is more commonly found that you have to put work into understanding all three planets and your element and working with the strengths of your trine to find the benefits of your birth.
