The trine aspect is 120 degrees. I tend to give it an orb of 7 degrees. It is considered an aspect of “ease.” Trines are pleasant, and while generally considered positive, I tend to consider them slacker aspects. Trines are great when they relieve the tension of more difficult aspects, giving respite between periods of work, but they can also result in slacking off from work that needs to be done. In this case they become a refuge of the lazy, enablers in escapism.
There’s a fine line between rest and avoidance. Like I said, trines are considered positive, but some of the most capable people have few or no trines in their chart. Some of the most inveterate ne’er do wells have many. Like anything it’s all in how you use it. A trine is an asset; it can be used well, held miserly, or squandered. You can use it like a tool, a relief from work and a way to recuperate between life’s bouts, or you can use it to pick your teeth while you lie on the couch and yell for someone to bring you the tv remote you dropped while scratching your ass.
Do you have trines in your chart? What do you think, are they helpful or lazy-making for you?
