Nadir and the Opponent in combination with the Elder-tree are indicative of a health problem. It doesn't have to be something major, it can be as mundane as a simple hangover; it doesn't kill us but oh dear can we feel awful by it! Since I attended a party myself last night I do admit that I am a bit pre-occupied with hangovers this morning, and the Oracle seems to resonate with that... So there we have it: take care of your health today and always try to make the kind of choices that will make you feel good the next morning!
Don't just read the future; help create it!
