The Devi Bhagavatam and Devi Mahatmya in Markandeya Purana are the sources of all the Navaratri Devi worship mantras and rituals. The famous shlokas "Sarva Mangala Mangalye"... etc. come from there.
In this excerpt, the Devi is extolled as the One who receives all the sacrificial offerings in terms of "Swaha" and "Svadha", as these incantations please all the gods and the departed forefathers, whose worship through Yagna is our bounden duty.
Anyone who misses these extensive interlinks in our scriptures from the Vedas (divine eternal scriptures) to Smritis (rules of conduct), Puranas (mythologies) and Prakaranas ( amplifications and depictions) is missing the wood for the trees.
