…the Prophets are able Physicians and informed of the
mysteries of the universe. They have Their finger on the pulse of the world,
and They diagnose and foresee the ailments and illnesses which are to come. It
is from the appearance, signs, and conditions of the universe itself that They
infer these mysteries. Thus, when an able physician notes certain signs and
symptoms in the body of a patient, he diagnoses future ailments, illnesses, and
conditions. This proceeds from his knowledge, skill, and power of inference.
