The trine
A trine is ease between two parts of you that cooperate without effort: two planets a third of the circle apart, in signs of the same element, a natural gift.
There is something you do so easily that you have never given yourself credit for: the right word to a stranger, the steady hand, the tune you can pick up after one hearing. Other people see it and ask how you do it, and you have no answer, because nothing resisted. That is a trine.
Two bodies 120° apart sit in signs that share an element, fire with fire, earth with earth, and so understand each other without translation. Old astrologers called it the luckiest of the aspects, and it is, with one condition: gifts that come easily are the ones most likely to go unused.
In your chart
Trines are counted at 120°, with 7° allowed either side, or 9° with the Sun or Moon, and the orb is written down. Blue on the wheel, a small triangle in the aspect grid. A trine to the Sun is a talent that feels like part of who you are. A trine between the Sun and Moon is an inner agreement between what you want and what you need, and it accounts for the calm some people carry without effort.
From a real analysis

You have more support than you think. Your feelings and your sense of meaning cheer each other on, so hope comes back to you after a low day. Your feelings and your private intensity agree as well, so you feel things fully and recover. Your heart and your public life are on good terms, which means people trust you because they sense the kindness is real.
Themes
A trine is a strength that does not know it is working. Moon trine Venus is an easy affection; Mercury trine Jupiter is a mind that learns broadly and speaks with confidence; Mars trine Saturn is energy with discipline built in. The element shared by the two signs gives the flavour: fire trines are enthusiastic, earth trines practical, air trines articulate, water trines intuitive.
Because nothing resists, the risk is complacency. The talent is taken for granted, the ease turns into laziness, and you assume that everyone finds this simple. Trines soften the hard aspects around them, so it is worth reading them together.
Three in a triangle
Three bodies that are each in trine to the others form a grand trine, a closed triangle in one element, where the ease goes round and round with nothing to push against.
How the analysis treats it
Trines are listed with their orbs and discussed in both bodies’ chapters. The analysis names the ease and asks what you do with it.
Your chart records how close to exact each aspect is, so the analysis can give a close one more weight than a loose one.
