Major Aspects
The five major Ptolemaic aspects describe angular relationships between planetary functions.
△
☌ 0°
Conjunction
unites two planetary functions in the same region of zodiacal longitude; it is not automatically easy or difficult
⚹ 60°Sextile
describes a cooperative opening that still benefits from deliberate participation
□ 90°Square
creates friction that can become conflict, urgency or competence through repeated adjustment
△ 120°Trine
allows easy circulation between functions, though ease is not identical to mastery
☍ 180°Opposition
organizes experience across a polarity and often exposes what is projected onto another person or situation
