She who removes death
She removes the death of her devotees
She destroys the death of Her devotees.
Mṛtyu means death. Only somebody without death alone can give the boon of deathlessness. Here death also means rebirth. She does not allow Her devotees to be reborn. This means that She destroys the karmas of Her devotees. Devotee does not mean a person who performs external rituals. One who is able to identify himself with Her is called a devotee and this stage can be attained only by perpetual meditation.
