Describe symbolism in Luther by John Osborne

Perhaps the most notable symbolism that Osborne uses in Luther is Luther's poor physical health. He suffers from seizures, insomnia, boils, and chronic constipation. His pains express his mental battles, and his inability to purge himself bodily represents his difficulty breaking free from the church's beliefs. Luther himself views his religious upheavals in terms of the physical body. When he finally formulates his own doctrine, it is while experiencing another bout of constipation; with the realization that "The just shall live by faith," Luther recalls, "My pain vanished, my bowels flushed and I could get up."
