The One who holds the Skeletal remains of the Human bones in her hands.
The One who stands at the final edge of the bodily end.
The One who holds the Nara-Mund, which here denotes the final resting of everything that is birthed.
The One to who is the final destination of all living and non-living entities, on the Mrityuloka.
Anyone born, will finally one day have to become the skeletal remains in her hands, until that state is reached.
However this is guaranteed only with intense sadhana, and dissolving one’s karma.
The cycle of birth and death continues till then.
Hence the name, NARA-MUND-HASTA-SASTA CA
