Though crew is based on Markandeya Purana, The direction and narration of whole story is totally independent of Markandeya Puran.
Chandi stands for the embodiment of ferocious "shakti" or the female form of cosmic energy. Bilas comes from vilaas which can also be described as chronicles/descriptive/heroics, Ukati means on, and Charitar means characteristics and function. So, Chandi Charitar Ukti Bilas means "Discussion on characteristics and functions of Chandi".
Ukat(i) bilas is divided into eight cantos, comprises 233 couplets and quatrains, employing seven different metres, with Savaiyya and Dohara predominating. In the former, the source of the story mentioned is Durga Saptasati, which is a portion of Markandeya Purana, from chapters 81 to 94.
The language of the composition is Braj. Ukti Bilas was composed at Anandpur Sahib, before 1698, the year when the Bichitra Natak was completed. The concluding lines of the last canto of Chandi Charitra Ukti Bilas as included in the Dasam Granth manuscript preserved at Patna, however, mention 1752 Bk / AD 1695 as the year of the composition of this work.
