Dakshina Kali is the most widely worshipped form of Kali, especially in Bengal: dark as collyrium, four-armed, her left hands holding a sword and a severed head, her right hands granting fearlessness and boons, standing on the still body of Shiva. “Dakshina” means both “the southern, right-hand one” and “the generous one who gives the reward”.
This hymn praises that form detail by detail — her loosened hair, fearsome teeth, the garland of fifty heads (the fifty letters of the Sanskrit alphabet), the ornaments of bone, her smile amid the blood — and calls her by the names of the great goddesses: Bhairavi, Durga, Uma, Brahmi, Vaishnavi, Chamundi, Tara, Chhinnamasta.
Then the tone changes. The devotee asks her, as a mother, to remove their foolishness and give them prose and poetry, logic and grammar “without study”, victory in the assembly, wealth, long life, family — and liberation at death. The sanskritdocuments.org edition notes that many of its verses are shared with other Kali hymns; it is a compiled hymn rather than a single ancient text.
