have you ever been to aplace that hasn't phisicly been created to be an altar, but has the power like it one? or has anyone every tride to create an alter without anything but intention and emotion? No objects, ritual, No aragment of material found, nothing?
I think it can be done. I imagine it would have to be in nature, or at least outdoors even in a man made area. And simple meditation at or about the spot could push energy there. Like when you are on a nature hike and you find a place that draws you in, for no reason but the energy of the space? There is a place like this in Minnesota, in Minneapolis when you hike under Minnehaha Falls (note: this is dangeruse an illegeal, but i don't know one person who hasn't done it...) There is no trash, markings, araging of stones or anything but the power and engery that is there, it's like you have gone to the spirit, insted of asking it to come to you. Oh, my picture is of me in that spot... huh...
