She is accessing something that she can perceive right now. And that is what works about processing. We need to keep the person perceiving more and more. Words and language sometimes make it tricky to know what is going on, unless you use your own perceptions at the same time. A person might give you what appears to be very precise and specific descriptions and explanations, where they really don't refer to anything.
Words are only useful when they refer to actual phenomena.
Most people will walk in and present their problem in vague distorted generalities and nominalizations. The facilitator will work on making the generalities more specific, bringing all the hidden material to light, establishing what can really be perceived, and so forth. That in itself is a valuable process. But also, we need to know what is there before we can take a decision on what to do with it. Just as often as not, the situation will vanish as soon as we discover what it really is.
