You were expecting more 毛 stuff? I will try next time. haha.
After seeing your post, I went back to the book but there is not more about it there. But actually I am more confident this ecstasy was more in a sexual/sensual sense than I thought because I assume the Caller was a man and the text indicated only women fainted. haha.However, you are right, ecstacy seems to be more related to religious or emotional feelings. I guess I was misled by the drug name ecstacy, sex and drug seem to be twins that always appear together. haha.
