You may see it has been said [486, 488, 493] that the universal heaven relates to the Body of our Savior, Who governs the universe as if it were His body, thus without any difficulty; and that the universe would be dispersed if all and the least things did not relate to His body and were not controlled by Him. In His body are two kingdoms, so to speak, just as in the human body; one pertains to the heart and the other to the lungs. The one pertaining to the heart is called heavenly, and the one pertaining to the lungs is called spiritual. These two kingdoms are united in a wonderful manner; and the one and the other govern in every single region [of the body], though each in its distinct way.
