Karmic Astrology is practiced by some astrologers who believe in reincarnation though the concept of Karma is not always associated to Indian religions.
 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.
 Some karmic astrologers have professed they can read the person's karma in a Natal chart by studying "in particular" Lunar nodes and retrograde planets.
 Other astrologers, such as Dane Rudhyar's protégé Alexander Ruperti, have lectured that "everything" in the Natal Chart is karmic.
