In the sign of Libra the universal mind – the soul – expresses its genius for relationships, that is, its power to harmonize diverse elements in a unified, organic way. Libra is the soul’s power to express beauty in all of its forms. And where is beauty if not within relationships? Beauty does not exist in isolation. Beauty arises out of comparison – out of the just relationship between different parts. Without a fair and harmonious relationship there is no beauty, whether it in art, manners, ideas or the social or political forum.
There are two faculties humans have that exalt them above the animal kingdom: their rational faculty (expressed in the signs of Gemini and Aquarius) and their aesthetic faculty, exemplified by Libra. Without an aesthetic sense we would be little more than intelligent barbarians. Libra is the civilizing instinct or urge of the soul.
