People are more cooperative if the feelings are backed up by visualizations and words. If things look different, and we have good explanations for why they must be different, well, then maybe one can allow oneself to feel different. And, the feeling different is the result that we are after. Visual and auditory information is at higher frequencies than feeling. They are easier to change and are more localized.
Feelings are more difficult to change and more general.
However, the feelings are the foundation without which nothing really happens. What happens is basically what you feel like happening. Any work that you do with a client is validated by feelings. If she feels different and particularly if she acts different, then we got somewhere. If she speaks different and she sees different pictures, that is good, but we might not have made changes that will actually manifest.
