I have a question that has been puzzling me for quite sometime concerning candles and spells. After the circle has been cast and you do your ritual, part of which is lighting a candle and of course you want it to burn completely (this is for a short spell not a long term big candle), but is it okay to close your circle while the candle is still burning? For some reason this doesn't feel right, but at the same time sitting potentially for hours seems just as bad if you're just staring at the flame waiting... Anybody who could shed some light on the topic because I have yet to find an answer in any 101 books or more advanced sources.
