Sacred space is by definition liminal space. Because we are not in control and not the center, something genuinely new can happen. Here we are capable of seeing something beyond self-interest, self-will, and security concerns. True sacred space allows alternative consciousness to emerge.
I remember as a boy standing at the side of a gorge watching the swift, shallow water and a girl standing in it up to her knees. Everything was settled and at peace in the sunlight. As I watched the hills began to sing -- I could hear them as an indistinct choir. Then they began to shimmer and dance. It seemed clear that we were linked -- hills and humans -- in a deep, objective way. And this connection made life true, and my usual fears irrelevant.
