Rumi speaks about paradox in the quote introducing the poem. We often think of entrances as being an external portal but, when we seek sanctuary, we turn in looking for the entrance to that sanctuary. The entrance is inside us leading further inside.
As the poem suggests, to be human is to be sacred. It is the coming together of two worlds, one outside and one inside. The inner one is much harder to reach as we try opening the door the wrong way quite often. We push out rather than turning in and pulling gently revealing light from the inner sanctuary that shines on us as we sit quietly waiting for silence to speak.
