Geometry
Exact angle: 120°. Lúmina working orb: 8°.
Interpretive function
Allows easy circulation between functions, though ease is not identical to mastery.
Why the planets matter
The aspect describes the relationship between functions; the planets tell us which functions are negotiating. A Venus–Saturn square is therefore not the same problem as a Mercury–Mars square.
Orb policy
Orb practice varies among astrologers. The numbers above are Lúmina v1 reproducibility standards rather than claims of universal agreement.
Ease is not the same as development
Trines connect signs of the same element, allowing functions to circulate without requiring much translation. That fluency can be a real resource, but an ability that never encounters resistance may remain unconscious or underused.
Applying and separating
An applying aspect is moving toward exactness; a separating aspect has already perfected. This distinction can change emphasis and timing, but it does not erase the aspect geometry or the condition of the planets involved.
Natal aspect versus transit
In transit work, a trine can make a function easier to access or integrate. The responsible interpretation asks what can be done with the ease rather than assuming an external reward will arrive automatically.
Interpretation checklist
- Name both planetary functions.
- Check sign and house condition.
- Measure the actual orb.
- Distinguish natal pattern from temporary transit.
- Confirm the symbolism against observed context.
Three concrete examples
Sun–Jupiter can circulate easily between identity and confidence; Mercury–Saturn can support structured thought; Venus–Moon can make value and emotional rhythm mutually legible. Ease still needs deliberate use if it is to become skill.
What not to conclude
An aspect is not an event generator. It describes geometry between functions. A natal aspect cannot prove a diagnosis, relationship outcome or future incident, and a transit requires actual natal contact and context before a specific claim is justified.
