He values it at its proper worth, when he loses it awhile. When health fails man, and the body fails to do his bidding, life becomes tasteless and tedious to him and depression of spirit hangs over him. Then on his bed of sickness, he curses his existence and yearns for health. Keep me healthy and sound and strong in body to the day of my death, Ahura Mazda. When old age creeps on me and health begins to fail, I will hourly pray unto thee to give me the soundness and strength of the body that once were mine, even as Rustom, the rider of matchless Rakhsh, prayed unto thee in the hour of his need to give him back the strength, from the surfeit of which he had suffered in his youth and from which thou hadst relieved him at his prayerful request.
Health gives liveliness and cheerfulness, superabundant energy and exuberant optimism.
Give me soundness and vigor and agility of body to work strenuously for the furtherance of good and to carry on a vigorous warfare against evil. Give me, I beseech thee, O Giver of health, a healthy body to nurture a healthy mind to enable me to lead an active and industrious Zoroastrian life in the discharge of my life's duties.
