PURPORT

Generally the goddess Kali is offered food containing meat and fish, and therefore Kasyapa Muni strictly forbade his wife to take the remnants of such food. Actually a Vaisnava is not allowed to take any food offered to the demigods. A Vaisnava is always fixed in accepting prasada offered to Lord Visnu. Through all these instructions, Kasyapa Muni, in a negative way, instructed his wife Diti how to become a Vaisnavi.
