mirroring

One of the fundamental things to know about processing is that you would FIRST get into rapport with the person, and THEN you would do something for her. Another way of saying this is Pacing and Leading or 'Mirroring'. 

Pacing is basically that you go along with whatever the person is doing at the time. You match where she is at. If she is bored, match her boredom; if she is full of energy, be full of energy; if she is talking slowly, talk slowly. You don't have to do exactly the same, and often it would be unhealthy for you to do exactly the same. But you can always match something about you with something of her's. If you do this smoothly you will both feel that you understand each other to a certain degree. 

If that was all you did, getting into good rapport, then nothing much would come out of it. You might both have a pleasant time, but it wouldn't really be a session. It probably wouldn't be anything a client would pay money for.

To make it a session you need to take the client somewhere where she wouldn't have gone by herself. Or at least you need to take her there faster than she would have gone there by herself. The action of taking her somewhere is what is called Leading.

Leading is whatever you say or do that is intended to get the client to change Source: Transformational Processing Institute
