The poem has four stanzas of 9 lines each, for 36 lines (double 18), not counting the epigrams from Genet. Each line has 9 syllables. The total number of syllables is 324, plus the 36 lines, equals 360—the number of degrees in a circle. Chai, Hebrew for life, equals 18 according to gematria. So, 36 lines, double 18, is double life.
