Astrologically the Sun is usually thought to represent the conscious ego, the self and its expression, personal power, pride and authority; leadership qualities; and the principles of creativity, spontaneity, health and vitality; the life force. The sun also involves creative enterprises that are a projection of the person, from art and business to having children and parenthood (especially fatherhood). It also rules the fun side of life from sport and recreation to holidays and social events. In short, any occasion that 'allows us to shine'. In medicine the sun is associated with the heart, circulatory system and the thymus. Philosophy and travel are also ruled by the Sun. Healing the energy of the Sun in your life will help your heart, your travels, your ability to have fun, your business, and many other endeavors.
