"***UNITING with a brother's mind prevents the CAUSE of sickness, and perceived effects***. ***Healing is the effect of minds that join***, as sickness comes from minds that separate. The miracle does nothing just because the minds ARE joined, and CANNOT separate. Yet, in the dreaming, has this been reversed, and separate minds are seen as bodies, which ARE separated, and which cannot JOIN."
From the vantage point of someone who sees themselves as "separate", healing another person suggest you must give them something which they lack, which you have, which sets you apart, and only they will be changed by the giving. This is actually part of the unhealed healer's mindset. An unhealed healer is someone who is not having a shared identity, is body identified, sees themselves as separated off and different, and believes they have what others lack. The "giving" then is on the basis that what they give will not be received, and so it has limited helpfulness.
I'm seeing more now that in ACIM, true miracle working really entails a joining and sharing, in which the minds have to actually kind of merge together in oneness, there has to be an openness and trust, a sense of mutual identity and mutual benefit. The two minds both recognize their oneness and share the love. Love isn't something exclusive. Both of them have to be immersed in the love and share it, the minds have to be connected and the sense of self has to be inclusive.
Both the giver and the receiver must benefit because miracles have a "universal" quality to them. They are about wholeness, and wholeness means a shared oneness. To really heal another then is in part to heal oneself, and to recognize there is one shared mind, one shared self/identity in christ, and to see your neighbor as part of yourself. This "merging" with another to join minds and undo separation is quite different to the idea of sending "love messages" across the gap of spacetime. The sense of self as "separate" has to be put aside in order to heal.
"No mind is sick until another mind AGREES that they are separate. And thus, it is their JOINT decision to be sick."
"You HAVE done miracles, but it is QUITE apparent that you have NOT done them alone. ***You have succeeded whenever you have reached another mind, and JOINED with it.***"
"But, having OBSCURED it, the light in ANOTHER mind must shine into theirs, because that light IS theirs."
"The power to HEAL the Son of God is given you, BECAUSE he MUST be one with you. ***You ARE responsible for how he sees himself. But reason tells you it is GIVEN you to change his whole mind, which is one with YOU***, in just an instant. And ANY instant serves to bring COMPLETE correction of his errors, and make him whole. The instant that you choose to let YOURSELF be healed, in that same instant is his whole salvation seen as complete WITH yours."
Give someone a mind-hug.
