The subject of astrology in the School of Eckankar has two main bases of Karma and reincarnation. Karma or the very law of action and reaction can be called the moral basis of the Eckankar. The totality of this law is accepted by the reason and tradition. But yet what casts doubt and therefore a serious damage to this law would be a tight connection between Karma and Incarnation in the School of Eckankar. This is because the ECK believes that Karma is incarnated through the transmigration, and moves from a birth to another one and this long way is continued up to the constellations. Therefore, in this writing and while explaining the Karma and accepting it in its totality, various types of incarnation are explained, and then it will be studied and criticized based on the teachings of Islam.
