Srimati Sita Thakurani is to be worshiped just as much as Sacidevi herself, as the mother of the universe. She is the eternal wife of Sri Advaita Acharya. She was the daughter of Sri Nrishinga Baduri. She was married to Sri Advaita Acharya in Phuliya Nagara.
After their wedding, Advaita Acharya went to Nadiya, to live in Shantipura. Sita Thakurani was always absorbed in vatsalya prema for Sri Gaurasundara Prabhu, and, out of parental concern used to instruct Jagannatha Mishra on how to care for the boy. Sri Krishna Dasa Kaviraja Goswami has described the birth celebration at the house of Jagannatha Mishra upon the advent of the Lord, giving special attention to the position of Sri Sita Thakurani. Advaita Acharya's wife, worshipable by all the three worlds was Sita Thakurani. Taking the Acharya's orders on her head, she had come to take a look at this new child, this jewel of jewels, and to offer him presents.
