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.
Serious spiritual practice is more than serene walks in the woods, lit candles and incense. You have to be committed. Your have to be willing to enter into your own darkness and transcend it.
