The myth Mudiyettu stages turns on a single, deliberate gap in a god's promise. The demon Darika secures from Brahma a boon that no man, in any of the fourteen worlds of Hindu cosmology, will ever be able to kill him, and sets about abusing the near invulnerability that promise seems to grant. Shiva, asked to close the loophole, does not break Brahma's word; he reads it literally instead, observing that the boon says nothing at all about a woman, and declares that the goddess Kali, in her fierce form as Bhadrakali, is free to do what no man can.
The battle that follows is Mudiyettu's climax, staged with a ferocity of movement and percussion meant to convey a genuinely uncertain contest rather than a foregone conclusion, before Bhadrakali kills first Darika and then his general Danavendra. The story functions, in the temples where Mudiyettu is performed, as more than a colorful legend: it is the founding narrative of the Bhadrakali cult itself, explaining why the goddess is worshipped in her ferocious aspect at exactly the temples where the dance is staged, and the annual re-enactment is understood locally less as a historical dramatization than as a renewal of the goddess's own victory, performed again each year so that the protection it won is not allowed to lapse.
