How do you communicate with spirits?

I AM NOT 100% SURE ABOUT THIS: there are stone that you can buy at gem shops (not sure what they are called) but they are shaped like small pyramids. if you light some candles and take loads of deep breaths and have a few small bowls of water around you, concentrate really hard on who you want to talk to: the way they look smell sound etc. if you don't already know, you would by now (if you have done what i said) are surrounded by all the elements (earth-the stone, water, fire, air-breathing) the only one that isn't there - that you know of - is the spirit. the elements and your thoughts will call to the spirit, it may take some time for him/her to reach you so be patient; it may even take days. keep thinking about them and they will find you. have an open mind and even though you may not be able to see them, you might hear them (or the other way around.
