Boksi

A Boksi (Nepali: बोक्सी) is a person staying alone and has knowledge of witchcraft, "Tuna Muna" and Tantra. According to Tantra-shastra and Shivapurana, Boksi is a lady who is different from normal god or goddess and has her own language. Boksi has a divine power and is capable to heal various diseases. A Boksi is capable to differentiate god, goddess, ghosts, "Pret", "Pichas" or "Dankini". She is able to call any of the goddess or witches and ask them to do a job for her. According to mythology, Parvati, the wife of Shiva was the originator of Boksi knowledge. She gave this power to seven of her sisters. From the youngest sister, this knowledge is believed to be transferred to the humans. 
Mostly elderly women are the most likely to have been accused of being a Boksi.
