The Poison Damsel (Sanskrit Viṣakanyā) is a literary figure that appears in Sanskrit literature as a type of assassin used by kings to destroy enemies. The story goes that young girls were raised on a carefully crafted diet of venom and antidote from a very young age, a practice referred to as mithridatism Although many would not survive, those that did were immune to other poisons and their body fluids would be poisonous to others; sexual contact would thus be lethal to other humans. There also exists a myth that says a Vishakanya can cause instant death with just a look or touch. They usually kill their targets by seducing them and giving them poisoned alcohol
This I imagine to be an angel of death luring the deceased spirit to the spirit world. Her beauty and allure so powerful that the spirit can't resist ! Her beauty is a weapon I suppose. Her body art suggest the life cycle of birth and death (caterpillar and butterfly/Spider skull represents death and the web of life) The jackal is the scavenger hence it is her pet!
