Surely most of us were taught as small children that we had to share. The stroke of genius here is that the Sharers realize we have no choice. Because we are utterly interdependent upon others, what we do, we share. As teachers or students, we share learning. As killers or victims, we share murder, and so on.
Mutuality is the process of loving and is a way of speaking of love.
It is the experience of being in right relation. Experientially, mutuality is a process, a relational movement. We become bearers of God. Not perfectly, but authentically. In these terms, each Sharer is a bearer of God, and the whole, Shora, is their God.
