The Three Modalities in Astrology #
The three modalities, Cardinal, Fixed, and Mutable, describe how energy is expressed and utilized. Also called quadruplicities (because each contains four signs), modalities reveal whether a sign initiates, sustains, or adapts. Understanding modalities adds crucial depth to sign interpretation and helps explain why signs of the same element can be so different.
