P.528 - §5 Perhaps I can best suggest to Urantia minds something of the nature of these beautiful and serviceable creatures by saying that they embrace the combined traits of a faithful horse and an affectionate dog and manifest an intelligence exceeding that of the highest type of chimpanzee.  And they are very beautiful, as judged by the physical standards of Urantia. They are most appreciative of the attentions shown them by the material and semi-material sojourners on these architectural worlds. They have a vision which permits them to recognize--in addition to material beings--the morontia creations, the lower angelic orders, midway creatures, and some of the lower orders of spirit personalities. They do not comprehend worship of the Infinite, nor do they grasp the import of the Eternal, but they do, through affection for their masters, join in the outward spiritual devotions of their realms.
