Religious Ecstasy
Today's translation was...well...it was interesting.
I admire people who are willing to suffer for the right thing; I respect those who die for their faith so long as they do not circumcision or even here. I do not even want to know what it was like to castrate yourself in general, let alone with a sharp flint before modern medicine.
I think ecstatic worship, especially ritualistic dancing, adds something to the worship service. For instance, you're actively awake during said service, which can be a key to enlightenment. Besides, music and dancing adds to the fun and excitement and aura of the ritual in question.
However, religious ecstasy does have its drawbacks, at least in Greco-Roman mythology (which could have been written from anti-mystery cult propaganda or to portray real events or enforce piety). For instance, Bacchus had his own cousin's mother rip his head off because Pentheus didn't honor him.
Here's a link on religious ecstasy in case you're interested.
