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.
In praise of redwoods, ancient trees:
I think that could the weary world but know
Communion with these spirits breathing peace
Strangely a veil would lift, a light would glow,
And the dark tumult of our lives would cease.
