While Chiron is only a comet, it does receive a great deal of attention, including during its retrograde period.  Chiron is known as the Wounded Healer, and that healing can be emotional, mental, spiritual, and even physical.  That which needs healing within you will come to light during this retrograde, no longer being buried, but coming to the surface, in order to help you transform and bring about the necessary healing you need.  This is not something which totally occurs within, others can trigger these old wounds, which may be very deep, forcing you to recognize, old patterns, including within relationships, This is a bit of a karmic undertaking, at times uncomfortable, but to relieve oneself of these old wounds can indeed be very healing.
