When my flame is low because there is too much wax I take a little bit out & put it in a empty tea light candle holder (enough to fill 2/3 if it too much wax & save it for later) or I put foil around the candle and create a small hole at the top, gives the whole candle heat to melt more wax. If it burns enough to expose more of the Wick I take the foil off if not I leave it on. I put the foil on it after I’m done chanting
posted pictures too. hope this helps y’all !
