For example, the playful little boy can receive assurance that he will have time and space even if you become a powerful executive. And make sure you keep your word. The little girl can learn that loving healing sexuality is good for all of you as an adult woman. You can also ask for signs that let you know that the parts are on board. You might just ask that a finger move by itself if a certain part is in agreement and giving permission.
Some people can make great use of such signal systems.
Other people can't achieve such aware communications and have to take it more on faith or more subtle communications. The subliminal messages on all the tapes have a permission component. Winning is safe. For even more effectiveness, you can create lists of your own and add them to your sessions. And focus some different permissions to different parts of yourself.
