Sri Matre Namaha
Pāpanāśinī – The One Hundred & Sixty Seventh name in Lalitha Sahasranamam.
papam nasayati iti
She who destroys sin.
Pāpanāśinī : Papa + Nasini = Papanasini
Papa means sin / peccadillo and Nasini means destroyer / destructive force
She completely destroys the sins of Her devotees, who repeat Her holy hymn.
Devotee is one, who always thinks about Her not only at the time of reciting mantras, not only at the time of performing rituals but in all three stages (sleep, dream and deep sleep) associated with Her continuously. For such a devotee mantras and rituals are not required. It is also presumed that Her devotees will not perform those actions that are termed as sins. If knowingly someone commits a sin, She will not come to his rescue.
But why does she want to destroy the sins of Her devotees? Krishna answers this question in Gita IV.14 ‘One who understands this truth (refer the previous nama) about me, does not become entangled in the results of reactions of work (results of reactions mean karmas. The concept of karma is based on Newton’s third law – for every action there is an equivalent and opposite reaction. This equivalent and opposite reaction is karma.)’.She wants Her devotees to pursue the path of liberation for which sins are impediments.
How does She consume their sins? Chandogya Upanishad says ‘papmanah praduyante’ meaning all sins are burnt up. The Upanishad further says ‘such sins are burnt like dry grass thrown into a fire’. The point driven home here is that when She is worshipped with all sincerity, the devotee gets rid of all his sins except prarabdha karmas that have to be experienced.
