Most people are familiar with their sun sign and know that the sun plays an important role in the horoscope. However, common terms like self-expression or ego provide only an inadequate insight into this highly complex astrological symbol. The book thoroughly explores the many dimensions of the sun in the horoscope, from the sun as a symbol of fatherhood to its correspondence with identity, vocation, and spiritual values. The sun reflects a process of unfolding within life. At our birth, the sun is not yet radiant, shining, and fully blossomed. It is always in a state of becoming, and its development occurs in cycles. Continuous effort is necessary for the further development of the sun. With the help of the transits and progressions of the sun, anyone can gain clarity about this process.
