It is very hard not to equate ourselves with our body. Our entire sense of well-being is based on how the body is doing.
If my body is sick, then “I” am sick. If my body is attacked, then “I” am attacked. If my body is calm, then “I” am calm. If bodies I care about are doing well, then “I” feel good.
But we have our focus of attention in the wrong place. Consider this line from A Course in Miracles: “The body is the instrument the mind made in its efforts to deceive itself.”
In other words, the body is not an independent entity that experiences pain and joy. The body is nothing more than a projection from our mind. And its purpose is to keep us rooted in the misguided belief that we are here in the body and that we can suffer.
However, since the body is a projection from the mind, when we make a different choice in the mind against the ego and for the mind of spirit, then our bodies become classrooms for learning and channeling love. And our experiences in the world are shifted from pain to peace.
