Henri Nouwen, in The Wounder Healer, quotes James Hillman, who talks about the Jewish mystical doctrine of Tsimtsum, noting that
God as omnipresent and omnipotent was everywhere. He filled the universe with his Being. How then could the creation come about? … God had to create by withdrawal; He created the not-Him, the other, by self-concentration … On the human level, withdrawal of myself aids the other to come into being.
Nouwen elaborates:
when we have found the anchor places for our lives in our own center, we can be free to let others enter into the space created for them and allow them to dance their own dance, sing their own song and speak their own language without fear. Then our presence is no longer threatening and demanding but inviting and liberating.
