Here is what Devi says in 7th skanda, 39th chapter. https://www.wisdomlib.org/hinduism/book/devi-bhagavata-purana/d/doc57430.html
The Śāstras that are extant, as contrary to the Śrutis and Smritis, are all Tāmasa Śāstras, Mahādeva has framed these Vāma, Kāpālak, Kaulaks, Bhairava and such like Śastras for fascinating the people; else he has no object in framing them.
Why does Devi say that Vāma, Kāpālak, Kaulaks, Bhairava agamas are tamasic in nature. How do they contradict shruti? Why Lord Shiva has to delude the people? Which agamas fall under each of the above categories?
