In Vedic astrology, known as Jyotisha, the Navagrahas are the nine celestial bodies that influence human life on Earth. Each planet is believed to emit a specific type of energy that can affect individuals based on their positions at the time of birth and throughout their lives.

1. Surya (Sun): Represents vitality, leadership, and the ego. It influences confidence and authority.
2. Chandra (Moon): Governs emotions, instincts, and the subconscious mind. It influences moods and inner peace.
3. Mangala (Mars): Rules over energy, courage, and determination. It influences physical strength and assertiveness.
4. Budha (Mercury): Governs intellect, communication, and reasoning abilities. It influences learning and adaptability.
5. Guru (Jupiter): Represents wisdom, knowledge, and fortune. It influences growth and spiritual pursuits.
6. Shukra (Venus): Governs love, relationships, and creativity. It influences artistry and pleasures.
7. Shani (Saturn): Rules discipline, responsibility, and hard work. It influences maturity and endurance.
8. Rahu: Represents worldly desires and materialism. It influences ambitions and challenges.
9. Ketu: Governs spirituality, liberation, and introspection. It influences detachment and inner peace.

Understanding the Navagrahas helps astrologers interpret the influence of planetary positions on an individual's life and destiny. By studying their placements in a birth chart (kundali), practitioners provide insights into various aspects of life such as career, relationships, health, and spiritual growth.
