Trine
Two planets 120 degrees apart, four signs from each other, usually in the same element. The easiest aspect: the pair cooperates without being asked. Its gift and its risk are the same thing, ease.
The trine divides the circle by three: 120 degrees, four signs, and in most cases two signs of the same element, fire with fire, earth with earth. Shared element means shared instincts, so the two planets simply agree.
Trines describe what flows: native talent, luck that is really fit, the parts of life that work without supervision. The caution attached to them is old and fair. What costs nothing gets taken for granted, and a chart's trines can name gifts their owner never quite develops.
In timing, trines are green lights and smooth road. Enjoy them, and give them something to carry; ease with a task attached is how a trine earns its reputation.
