PURPORT

It is evident from this verse that the devotees of goddess Kali are not at all favored by her. It is goddess Kali's work to kill and punish the demons. Goddess Kali (Durga) engages in decapitating many demons, dacoits and other unwanted elements in society. Neglecting Krsna consciousness, foolish people try to satisfy the goddess by offering her many abominable things, but ultimately when there is a little discrepancy in this worship, the goddess punishes the worshiper by taking his life. Demoniac people worship goddess Kali to obtain some material benefit, but they are not excused of the sins performed in the name of worship. To sacrifice a man or animal before the deity is specifically forbidden.
