Just like there are four elements, there are three qualities (also called modalities) to the signs of the zodiacal circle. There are four signs for each quality, each one from a separate quadrant of the zodiac. This characterization is of great help to understand one’s character and interpret a certain planet in someone’s chart. Their most important and specific role is tied to astrology and timelines needed as an answer to a question.
Each of the three qualities has its speed and characteristic, and combines with only one sign from each element. This means that there are no two signs of the same element with the same quality. If we understand the nature of the element, it will be even easier to understand each specific sign through its combination with the quality.
Opposite signs share the same quality and this is their gateway to mend differences and discover how to incorporate each other’s philosophy into their own life. They share a similar pace in life, even though their element brings a difference in their speed. Each couple in the zodiac is presented by a connection of two close elements, Water and Earth, Fire and Air, and qualities represent a bridge between their worlds that helps them build mutual understanding.
