We ask someone who is grieving to first think about someone special who feels present in his/her life (although they are not physically present at the moment, and may be dead or gone permanently), and then about the person they are grieving about. Then we ask them to think of the two people simultaneously, and ask them to notice the submodality process differences between them. The loss will typically be represented as distant and separate in some way, and with a feeling of emotional emptiness, while the existing relationship will be represented with a sense of presence and emotional fullness.
There will typically be very important differences in the location of these representations in personal space. For instance, one may be close, to the left, and larger, etc. while the other is farther, to the right, and smaller, etc. There are usually many other differences. One image may be brighter than the other, or more colorful, or moving, one may be silent while the other has sounds or voices, etc. These are all differences that are completely independent of the content of the representations. Once these differences are known, it is a fairly simple process to transform a situation of emptiness and grieving into one of fullness and rejoicing.
Usually taking the image of the loss experience and moving it to the location of the experience of presence is all that is needed to transform the loss into an experience of felt presence. Typically the other differences in brightness, color, movement, etc., change spontaneously when the location is changed. If these other parameters do not change spontaneously, we simply ask the client to change them until the loss experience is fully transformed into an experience of presence.
When this transformation is complete, they will recover the good feelings that they had with the lost person. When this occurs, the client will often cry, but these tears are very different from the tears of loss. These are tears of reunion with the lost feelings, and it is important to allow the client to take time to experience them fully.
