In Vedic astrology, the Sun (Surya) is considered the soul of the universe, representing power, authority, self-expression, and energy. It is the planet's ruler, responsible for an individual's identity, ego, and willpower. The Sun is a karmic aspect that influences leadership, recognition, and the ability to shine in society. Understanding the Sun's role in a birth chart (Kundli) is crucial for predicting a person's confidence, success, and overall life path.
