The Moving Universe is designed for the student of astrology, and is the only book on transits that deals with both the mundane and spiritual interpretations. It is as much a spiritual teaching as it is an astrology book. The mundane (worldly) interpretation shows what is likely happening in the outer life. The spiritual perspective gives the interior lessons and challenges that the transits are bringing. Understanding these issues gives the student a deeper perspective on what's going on in the client's (or their own) life. Many students of astrology are on a spiritual path, and understanding the spiritual perspective will help them.
