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.
Inner peace is not found by staying on the surface of life, or by attempting to escape from life through any means. Inner peace is found by facing life squarely, solving its problems, and delving as far beneath the surface as possible to discover its verities and realities.
