Modern
Libra is a cardinal air sign ruled by Venus, the archetype of the diplomat, relational and fair, seeking balance and beauty. Wherever Libra falls in a chart, that area of life takes on this character: the air temperament (its way of meeting the world) in its cardinal mode (how it moves and changes). The gift is the sign's strength at its best; the work is balancing it against its opposite. At your best you live the sign's nature consciously rather than on autopilot.
Traditional (Hellenistic)
Libra is the cardinal air sign, hot and wet by the old qualities and reckoned a diurnal sign. Its domicile ruler is Venus, so Venus is the lord of any planet that falls here and of the matters Libra governs; Saturn takes its exaltation here. A planet in Libra must work through the sign's nature and answer to its ruler's condition. As a place in the chart it carries the diplomat, relational and fair, seeking balance and beauty.
Lean in — Express Libra's nature consciously and at its best.
Watch for — Run Libra on autopilot or only its shadow.
