intresting is it the oil made by dead human fat ?

If seeking anything from Ghost, must exchange with something which you feel cant afford to return.. Why not seek blessing from Deities.. Example as Nine Tails Fox Fairies.. She also a female guardians who wish people doing more good deed..

u can't know if "she" is sincere to help or "she" has something need u to help, and how if she help u but what "she" want u can't promise ...? usually this spirit they come and appear infront of normal human they come to u sure they need some help or some thing u own them, and ghost need to inhere human 'yang' engergy to continue as food what if u not enough ? lucky u just fall sick bad can cause ur live indirectly, human 'yang' engergy is not always consistence, it is vary from our daily activity we can't check our self when is the time we are power or week and you can't stop "her" to come close to u once u attach with "them" this is the most danger thing.
