Ouroboros
Writhing about in man’s mythologies
Is a completeness, itself to affirm
Scriven in the ancient cosmologies:
The self-ordained perfection of The Worm
The Samsara of the self-seeking soul
And a self-admiring self-causation
Itself entire, a universal whole
Devouring its tail in auto-phagation
But metamorphoses have come to pass:
The endless worm’s head is now up its own (self)
W. K. Kortas alluded to self-obsession as having one’s head up one’s own (euphemism), and a friend mentioned the Ouroboros, which appears in several cultural traditions, so here is your ‘umble scrivener’s variant.
