I wasn’t sure about the Santeria thing, it was just the one article (that I saw) but now I am sure it’s true.
I’ve never heard anyone I know or read anyone saying stuff about “clean spirits” other than reading about voodoo or or wicca/witchcraft stuff.
Un-freaking-believable! The White House will needs massive cleaning when they leave, plus it will reek of cigarette smoke.
It will reek of more than that.
A quick search did show lots of references between Voodoo and cleansing of spirits. I thought it was in a Christian church hymn as well, but that is “Create in me a clean Heart”. Although I imagine there are references in the Bible to folks with a clean spirit.
