Katyani as Vaishnavi Durga Deity is worshiped in Srila Advaita Acharya Prabhu House of Sree Shantipur Dham. Katyani Deity worship was started in Shantipur by the followers of Srila Advaita Acharya Prabhu in order to resque the stolen Radha Raman Deity.
Vrindavan Gopi’s performed Katyani worship in order to get Krishna, and they were succesful. Same in Shantipur. Advaita Acharya Prabhu’s followers follow the Vrindavan Gopi’s tradition and were able to "rescue" the stolen Radha Raman deity.
