This is not possible if we are always generating talk and ideas. It is hard to grow spiritually if we are never quiet. In order to have a receptive, spiritual attitude, it is important to let go of constant intellectual debate. The intellect is a tool. Science is a tool.
Discussion is a useful activity.
But entering into sabbath time, into a time of sacred rest, means letting go of these for a time. It means setting aside the active brain to some degree and listening to the heart. This can be hard for Unitarian Universalists to do, but I believe that spiritual maturity requires it. Reason is always part of the picture for us. And I believe this is our genius.
