Stellar Regent

The Stellar Regent (命元星) is the single most important planet in an Eastern Classical Astrology natal chart — the primary axis around which all other chart elements are interpreted.

Derivation chain: By day the Stellar Regent is the Solar Stellar Regent (命度主); by night, the Lunar Stellar Regent (身度主). For a day birth, the Sun's degree is carried across to the Life Palace, and the lunar mansion at that exact-degree (partile) point yields the ruling planet. For a night birth, the mansion is read directly from the Moon's own position. Each of the 28 Lunar Mansions carries a planetary quality (solar, lunar, or one of the five planets), and that planet becomes the Stellar Regent — the individual's cosmic source embodiment. The two methods are asymmetric: the day method adds a degree-to-Life-Palace correspondence that the night method does not.

Why "Stellar": The Stellar Regent is derived through the lunar mansion (a fixed stellar matrix) as the astronomical intermediary. It is not a direct solar principle, nor a purely zodiacal one — the stellar layer is essential to the derivation.

Why "Regent": The Stellar Regent governs the interpretation of the entire chart, echoing the framework of the Seven Regulators. It is the individual's primary Regulator, selected through direct energetic lineage from a specific stellar matrix.
