1. For Kali-puja: Eating remnants of ghosts

    Goddess Kali does not eat meat; she is the husband [wife] of lord Shiva and takes only His remnants. That offered meat is eaten by ghosts, and so those people are eating remnants of ghosts. They are not worshipping Durga strictly according to scripture.

    Srila Prabhupada, quoted in a letter from Aravinda to Satsvarupa, 28 Nov 1970.
