'Coatl look at our planet..where did we come from?? where did our minds develop? its a big rock!!! and we are discussing the uses of crystals and stones..not all of us need to have hard scientific proof that things are the way they are...and i understand that its our awareness and consciousness that directs our power...stones are focuses..but they do have a vibration..which everything has..except crystals..are crystalline and they have a more pure vibration compared to a handful of dirt..
