The only meaningful contribution the healer can make is to present an example of one whose direction [meaning decision] has been changed for him, and who no longer believes in nightmares of any kind (T-9.V.7:4).
That is the healed mind of the healed healer. Unhealed minds think that what heals is their wisdom, their hands, how they pray, the particular skill they have. Wrong. That is what attacks, because it reinforces the very thought system that is the source of the problem. To repeat, "The only meaningful contribution the healer can make is to present an example of one whose direction has been changed for him and who no longer believes in nightmares of any kind."
The core of all nightmares, as well as every experience in the phenomenal universe is the belief that the separation from God is real, and that separation and differentiation are the reality. This makes me different from you. If you are sick, I am the expert who can heal you. On the level of form, that may well be the truth, and I am not saying you should not avail yourself of that help. Just don't think it is healing. Don't think for one minute that it will take you home, that it undoes guilt, or even more to the point, that it undoes the belief in guilt. It doesn't.
