Heinrich von Ofterdingen's Karma: Stars, Magic, and Rationalism

To answer this we must return to the story of the Battle of the Minstrels. Heinrich von Ofterdingen takes up the fight against the others. They have already called the hangman. He is to be hanged if he loses. He manages to withdraw; but, hoping to bring about a renewed contest, he summons the magician Klingsor from the land of Hungary. He did, in effect, bring the magician Klingsor from Hungary to Eisenach. A new Battle of the Wartburg ensues and Klingsor enters the lists for Heinrich von Ofterdingen. Klingsor himself sings against the others, but it is quite evident that he is not battling alone. He causes spiritual beings to battle with him. For instance, in order to do so, he makes a youth become possessed by a spiritual being—and then compels the youth to sing in his place. He calls still stronger spiritual forces into play in the Wartburg.
