Om Dum Durgayei Namaha
Rough Translation: 'Durga is the Divine Protectress. Typically shown riding a lion or a tiger, Durga has a hundred arms, each with a different weapon of destruction. Yet her face is exquisitely beautiful to behold. The interpretation is that to the pious and the sincere seeker after truth, her sight can produce ecstacy and a variety of beautiful forms. But the negative, harmful or demonic, her countenance is as terrible as Kali, except she shows more weapons of destruction than Kali (who is described later).
Om and Salutations to that feminine energy which protects from all manner of negative influences, and for which Dum is the seed.'
