Inner Critic parts often seem to be very powerful and frightening, but this is often a front they put up to be able to do their job. When you get to know them, you view can often change dramatically. Here is an example of this:

Sarah was really frightened of her Inner Critic. It screamed and yelled at her and crushed her with its attacks and it power. It told her that she was worthless and would never amount to anything. She visualized it as a huge powerful monster with great muscles and a loud voice that was beating at her. However, once she got into Self and was openly interested in getting to know it and its positive intent, it gradually changed. It became smaller, less threatening and more reasonable. When she came to understand what it was trying to protect her from, her image of it morphed again; now she saw it as a frightened kid who was doing its best to act tough to prevent a terrible tragedy. It was afraid that if she felt OK about herself, she would put herself out in the world and get shamed. Therefore, she felt compassion and caring for it. She saw that the real Critic had been revealed, like the little man behind the curtain in the Wizard of Oz.
