34:5.2
On the inhabited worlds the Spirit begins the work of evolutionary progression, starting with the lifeless material of the realm, first endowing vegetable life, then the animal organisms, then the first orders of human existence; and each succeeding impartation contributes to the further unfolding of the evolutionary potential of planetary life from the initial and primitive stages to the appearance of will creatures. This labor of the Spirit is largely effected through the seven adjutants, the spirits of promise, the unifying and co-ordinating spirit-mind of the evolving planets, ever and unitedly leading the races of men towards higher ideas and spiritual ideals.
