Barbara Hand Clow in her book of Chiron. Referring to Chiron intercepted along the Virgo/Pisces axis on pages 191-192 Ms. Clow states,
“…Many find retrograde planets and interceptions hard to understand, but great progress is made as soon as it is clear that retrogrades are a time dynamic altering perception, and interceptions are a place dynamic altering perception. With an interception, the houses intercepted indicate a past and present life karmic dynamic; I.e., they show a past-life-karmic failure which will be dealt with in this lifetime no matter what.
