A
ceremonial act of
magick in various
esoteric traditions of
Christianity and
Paganism, a translation of "
orgy", which means the same thing. May or may not include
sexual activity,
flowers,
herbs,
candles,
music,
dance,
chanting, circle casting, etc.
Not always as a means of
spellcasting, a working can be merely for the purpose of marking an
anniversary, to honor a certain group, etc.
The Catholic Mass is one kind of working, some say the most powerful of all.
