DIFFICULTY OF ASCENDING TO THE SKY

DIFFICULTY OF ASCENDING TO THE SKY

125- ...And whomever He wills to send astray, He makes his bosom narrow and strained as if he was ascending into the sky.
6-The Cattle, 125

A person subject to spells of dejection and who feels strained is likened to a person who is ascending to the sky. We know today that during ascension, atmospheric pressure gradually decreases, rising blood pressure causing strain on the functioning of heart and veins topped by lack of oxygen, which in turn influences the lungs, making one feel constricted. If one persists going even higher, there comes a moment when the individual loses his life.

There were no airships or aircraft at the time of the Prophet. Torricelli was the person who in 1643 invented the mercury thermometer with which he demonstrated that the atmosphere exerted a pressure. To speak of a decrease of pressure at the time was out of the question. Nor was there reliable information about circulation of the blood or lungs. One can guess that men climbed heights and had difficulty breathing as they went higher and higher. In the verse, however, ascension is toward the sky. A person experiencing difficulty of respiration on top of the mountain he has climbed may attribute this difficulty not to the lack of sufficient oxygen at the high altitude to which he has climbed. The verse speaks of a process that takes place as one rises to the sky. The question is not of the experience one has on the top of a hill. Ascension to skies has a much wider connotation.

OPTIMUM PRESSURE AND OXYGEN FOR PERPETUATION OF LIFE
The oxygen and pressure ratio being ideal, a man’s bodily functions run across no difficulty from sea level up to a height of 3000 meters. At altitudes ranging from 3000 to 5000 meters, elevated blood pressure and difficulty breathing are experienced. At an altitude of 7500 meters, the tissues are badly in need of oxygen. Above this height, a person experiences a...
