It’s very important to have a strong SUN in the horoscope as it represents our soul and the life force. Sun is your self esteem and healthy ego. Sun is the Prana. He is the reason you are alive. In your horoscope, planet SUN represents your father. And its placement in your horoscope can tell a lot about your relations with your father . You love him OR hate him; he loves you OR hates you? Are you going to live with him OR send him to an old-age home? What kind of legacy you are going to get from him? Good human values, money, estate or nothing at all? How he behaves with you? Verbal abuse, sexual abuse, physical abuse OR love, care, sacrifice and compassion? All these things can be seen from your horoscope and the SUN in your chart.
