Heidel studied him. He was a Murtanian, and his branchial membranes were swollen and flared, which indicated excitement. His head was not bowed; instead, he was staring upward. Heidel followed the direction of his gaze, and saw that he was looking at that row of giassite illustrations which formed a continuous band of deities, passing along all the walls of the chapel. The man was staring at the one among all those illustrations which was now glowing with a blue fire. When his own eyes fell upon it, Heidel felt something akin to an electric shock. Then his extremities tingled and there came a feeling of dizziness. Not one of the old diseases acting up, he hoped. But no, it did not behave that way. Instead, there was a strange exhilaration, like the first stages of drunkenness, though he had had nothing alcoholic to drink that day. Then the place began to fill with worshipers. Almost before he realized it, there was a service being conducted. The feeling of exhilaration and power began to heighten, and then specific emotions appeared--oddly contradictory emotions. One moment, he wanted to reach out and touch the people about him, call them "brother," love them, heal them of their ills; the next moment, he hated them and wished that he had not just undergone catharsis, so that he might infect the entire congregation with some fatal disease that would spread like flames in a pooi of gasoline and kill them all in a day. His mind cycled back and forth between these desires and he wondered if he were going mad. He had never exhibited schizophrenic tendencies before, and his feelings toward humanity had never been characterized by either extreme. He had always been an easygoing individual who neither gave trouble nor sought it. He had neither loved nor hated his fellows, but took them as they were and moved among them as best he could. Consequently, he was at a total loss to understand the mad desires that suddenly possessed him. He waited for the latest wave of hatred to pass, and when the lull came before the next upswing of amity, he rose quickly and pushed his way to the door.
