How to understand it
Common angles include conjunction near 0°, sextile near 60°, square near 90°, trine near 120° and opposition near 180°. The allowed distance from exactness is called an orb; readers vary in the orbs they use.
An example
If two placements form a square, you might ask where two priorities feel hard to combine. It is an invitation to compare experiences, not a verdict that you are conflicted.
Use it carefully
Check the exact angle and orb before reading an interpretation. Near misses should not silently become exact aspects.
Try a reflection
Which two priorities are both real, even if they pull differently?
