We often think of the astrologer as a non-participating observer, someone who reports on the clients issues, timing, and choices. However, quantum physics tells us that the observer is actually part of the equation; the act of observation changes that which is observed. The implications of this are great. As astrologers, we cannot deny or otherwise avoid our roles as agents of change. So what do we do about this? How do we accept the responsibility of altering the lives of our clients? And where do we go from here?
