I use tarot and other divination methods (primarily the I-Ching/Book of Changes). It’s less about trying to get magical communication from some sort of magical realm or helper for me, it is more a way to organize my thoughts. Often times, the advice associated with each card is just generic good advice, and it prompts me to consider situations from other perspectives. I take some time to think about a problem facing me and use the cards as creative prompts for ways to solve that problem. No supernatural stuff involved.
Horoscopes are mostly just (hopefully!) good advice packaged in what can only be described as a crime against astronomy. They’re good to read, because they tell you what people want to be thinking about themselves.
