In normal communication the intention is for a message to be understood by the receiving party. One communicates in order to convey some kind of point.
In a processing session we are communicating with a slightly different purpose in mind. The facilitator doesn't particularly communicate to get her ideas through to the client. The facilitator is completely neutral and doesn't have an agenda of her own. What she is doing is that she communicates in order to activate the process of change in the client. She says what she does in order to make things happen. She asks the questions she asks in order to change the client's perspective. The messages that the client will get will ultimately originate within herself.
However, no matter why we communicate, the communication needs to arrive with the recipient. If we suppose that the recipient is at least partially present, the responsibility for getting the message delivered lies with the sender. The sender needs to notice when the desired recipient is available and must deliver the message in a suitable manner.
A process facilitator needs to be very proficient in delivering communications. She needs to be able to deliver a message as close to what she intended as possible. She needs to be precise at getting across the exact message, with the exact intensity she wants.
Getting a communication delivered is equivalent to sending a physical object through space. Something actually needs to go from the sender to the recipient. There is an energy that originates with the sender, traverses a certain distance, and arrives with the recipient.
If the energy object that is being sent only gets halfway then we don't have a full loop of communication.
The sender needs to propel the message object forward. She needs to want it to arrive. She needs to use the necessary amount of energy to make that happen.
One can also deliver a message with too much energy, too forcefully. Then the recipient gets overwhelmed, and might miss the message for that reason.
Delivery of spoken communication has something to do with the loudness and inflection of one's voice. However, that is not all of it. What is most important is the energy one is sending with the communication. The intention for it to arrive. Sometimes a whispered communication will go through loud and clear because it is intended to be received, whereas a shouted communication might not be heard because it had an imprecise or weak intention behind it.
There is a preciseness in the location one sends the communication to. A communication that just goes out vaguely in all directions is not as effective as one that is delivered precisely where it belongs.
A communication that is delivered with clarity and intensity directly to where the person is, can have a remarkable effect. To the recipient it can feel like a wake-up call. "Wow, somebody really got through to me!" It can activate new opportunities for change in an instant.
There are other important qualities required in delivered communication. For one thing the degree to which the sender is present will make a difference. If the sender is bored and uninvolved and thinking about other things, then she won't deliver an effective communication. If she is just repeating the same question she has asked many times before, then she isn't very effective. Even if she is incidentally saying some words she has said before she needs to be present with them and deliver them as if they have never been said before. The moment is always new, there is a unique situation here, and a unique opportunity for helping another person with communication. It is never, never a matter of robotically repeating questions.
A communication needs to be delivered naturally. That is, it must be the sender's own communication. If she gets the wording of a question or direction out of some procedure that she has studied then she still needs to make it her own communication. She still has to be aware of why she is saying it, what effect she expects, she has to intend for it to arrive, etc.
