Indeed, Edgar Cayce, a devout Christian, professed that the position of the planets at birth records the time spent by the souls on other planets (or perhaps their spiritual counterparts) in between incarnations.

Other astrologers, such as Dane Rudhyar's protégé Alexander Ruperti, have lectured that "everything" in the Natal Chart is karmic.
