Each morning one of the captors would come to the gate that encased them. The one that separated them from freedom. He never entered the gate. He never got close enough to touch it. He merely spoke. You are prisoners. There is no escape. And he walked away.
The next day and the day after that. You are prisoners. There is no escape.
Among these prisoners was one they called Mother. Mother was old, and blind, and deaf. No one paid much attention to Mother. She was one of them and completely harmless. Mother in her condition had never once heard the words, "You are prisoners, there is no escape."
One morning just after her captor came and went, Mother did something spectacular and freeing.
Mother made her way to the gate and with no effort opened it. Just like that. She opened a gate that had only been locked in the mind's of the captives.
