The Sun represents the core of who you are: the soul (atma), the ego, willpower, and your sense of identity and purpose. In the family it signifies the father. In worldly terms it rules authority, government, leadership, status, and people in positions of power.
The Sun also governs vitality and health, especially the heart, eyes, and overall life energy. A well-placed Sun tends to give confidence, dignity, and a natural ability to lead. A weak or afflicted Sun can show up as low self-worth, ego struggles, or trouble with authority figures.
Strength, Day, and Gem
The Sun is exalted in Aries, where its energy is strongest, and debilitated in Libra, the opposite sign, where it is weakest. It rules its own sign of Leo. The Sun is considered a mild malefic—hot and harsh in nature—but it is not destructive the way Saturn or Rahu can be.
The Sun rules Sunday and is associated with the colour orange or red and metals like gold and copper. Its gemstone is the ruby, traditionally worn to strengthen a weak but well-intentioned Sun. As always, gemstone advice should come from a qualified astrologer after studying the full chart, not from a single placement.
