text: I think you may be confusing things a little here.  You're really asking to very different questions without a purpose.  The Spiritualist movement of the early 20th century started out being about communicating with loved ones who had died.  Although some mediums were the genuine article (they could 'talk with the dead'), most were in it strictly for the money they got by fleecing wealthy and usually elderly women looking to talk with their dead husbands.  If you want an idea about this, rent the DVD "Ghost" with Whoopi Goldberg.  To the best of my knowledge, they do not hold a specific belief about 'elements', such as fire (or water, etc.).\n\nNow, if you want to focus your 'energies', that's another question all together.  You're not talking about 'stones', per say, you're really asking about crystals.  Again, the question is way too broad to even address here.  I've provided a link below that may illuminate you (only one of many online).  I HIGHLY recommend not 'playing' with things you don't know about.  Try to find a couple books...better yet, take a class!\n\nGood Luck,\nRev Debi Brady\nMetaphysical Minister
