What it isTrine
Two planets about 120° apart, energies flowing together.
Square
Two planets about 90° apart, energies grinding against each other.
What it answersTrine
'What talent do I have here?'
Square
'What must I work through here?'
Time scaleTrine
Ongoing ease; energy is always available.
Square
Recurring pressure points, often activated by events.
How to use itTrine
Use the talent on purpose; don't let it sit idle.
Square
Face the pressure and turn the friction into drive.
How they relateTrine
Both usually appear: trines give talent, squares give lessons — they balance each other.

The same two planets read very differently at different angles.

The takeaway Don't read squares as bad news — trines keep you comfortable, squares make you grow; both are gifts in a chart.
