Parsee is about to go to a shrine in the deepest night and cast death curse by nailing the doll representing the person she wants dead to a sacred object, nail going a certain body part pointing the spirit where the death should begin or cause death. Nailed to something like a tree or the shrine gate each night - the more the better, i think the usual peroid is a week, one daily.
I think you can be tried for attempted murder in japan for it but im not sure or at least an intent to murder.

The saint portrayed with a candle crown is almost certainly related to the tradition of the church waiting for the birth of Christ
In catholicism there are 4 candles and it is lit just before the altar, each candle for another week of the advent peroid, stacking with one extra each week until Christmas, symbolising 4000 years of the world since the beginning of the relation of God with humankind, waiting for a promised messiah. Each candle being a millenium.

She just seems to wear more than that.
I havent read much lives of saints, so I cant make out anything besides that.
The fact it is in december makes me very confident that this is the root.
