She is a black, hideous deity into sex, blood and extermination. A bit like a female Hindu dalek without the eye-stalk.
KALI has three eyes, four arms, vampire fangs and is bloated with the blood of victims. She is awful, terrible and horrifying. However, as we are constantly reminded by her followers, she does have some good points.
In fact, despite all those negative-sounding attributes, KALI is Mrs SHIVA, a stern-but-fair mother figure who maintains order and rewards seekers of the truth. Her destructive tendencies are aimed at the ignorant — she aims to purge stupidity and wipe out godless idiocy. So that’s all right then. No need to worry unless you are an atheist.
