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.
The point of passing time in solitude is to strip yourself bare, to discover what is essential and true. When you are stripped down to this point, you see how little you amount to. But that little is what God is interested in.
