Angles 147 stars and the sun and the moon and the elements carry out their functions, yet in reality it is carried out by angels. [Ā'īna-e-Kamālāt-e-Islām, Rūḥānī Khazā'in, vol. 5, pp. 133-137 Footnote]. Independent Existence of Angels. Our observation and our reflection and intelligence and thinking clearly show that for every grace there are intervening causes between God Almighty and ourselves, through whose intervention every faculty receives grace according to its need. This establishes the existence of angels and jinns. We have only to prove that for the performance of good or ill our faculties alone are not enough and that we are in need of external help and assistance which has supernatural effect. These helpers and assistants do not operate directly without any mediation. There are some mediatory means. The observation of the law of nature has established conclusively and certainly that those helpers and assistants exist outside of us. We may not be aware of their true reality, but we know for certain that they are neither the Almighty. Himself operating directly, nor are they our own faculties and capacities. They are a species of creation which have independent existence. When we name any of them as calling to good, we would describe him as the Holy Spirit or. Gabriel, and when we name him as calling to evil we will describe him as Satan or Iblis. It is not necessary that we should exhibit the Holy Spirit or Satan to every dark heart, though those who have insight can see them and they become visible in visions. [Ā'ina-e-Kamālāt-e-Islām, Rūḥānī Khazā'in, vol. 5, pp. 86-88]
