The brain appears to possess a special area which we might call poetic memory and which records everything that charms or touches us, that makes our lives beautiful. From the time he met Tereza, no woman had the right to leave the slightest impression on that part of his brain.Tereza occupied his poetic memory like a despot and exterminated all other trace of other women. That was unfair, because the young woman he made love to on the rug during the storm was not a bit less worthy of poetry than Tereza. She shouted, ‘Close your eyes! Squeeze my hips! Hold me tight!; she could not stand it that when Tomas made love he kept his eyes open, focused and observant, his body ever so slightly arched above her, never pressing against her skin. She did now want him to study her. She wanted to draw him into the magic stream that may be entered only with closed eyes. [..] She wanted to merge with him. [..] 'It’s not sensual pleasure I’m after,’ she would say, 'it’s happiness. And pleasure without happiness is not pleasure.’ In other words, she was pounding on the gate of his poetic memory. But the gate was shut. There was no room for her in his poetic memory. There was room for her only on the rug.
