“To be in the Kingdom is merely to focus your full attention on it. As long as you believe you can attend to what is not true, you are accepting conflict as your choice. Is it really a choice? It seems to be, but seeming and reality are hardly the same. You who are the Kingdom are not concerned with seeming. Reality is yours because you are reality. This is how having and being are ultimately reconciled, not in the Kingdom, but in your mind. The altar there is the only reality.” (ACIM, T-7.III.4)
The altar in our minds is the true reality. We are not concerned any longer with “seeming” to know reality; we do know reality. We both have and we are—what we are being is consistent with our having the Kingdom of God.
This is deep understanding, and it is hard to recognize on first reading. When we wish to be in the Kingdom, we can focus our full attention upon it, and when we do that, we are no longer “seeming” to know reality, but we are truly knowing reality. Attention, mindfulness, is a way home, a way to salvation, and, ultimately, a way to Awakening, or enlightenment.
What we are in our essence, in the inner altar of our minds, is reality. Nothing else really exists. There is no world, according to Jesus in A Course in Miracles. It is purely and simply illusion, projected from our minds outward in a world, as well, of illusory bodies. Of course, everything seems solid, but that is simply part of the illusion. Projection makes perception, as Jesus also says.
Many of us do not accept that the world is not real. But if we come to see that it is, we are immediately freed from its effects. We realize that there is nothing in an illusion that can ultimately hurt us, and so we stop being defensive.
Jesus also encourages us to avoid defense, saying that it makes what we are trying to avoid.
So there is nothing in this world that can hurt us in any real sense. We see blood in the illusion, but it is not unlike catsup in a movie. We are never ultimately harmed. The only real thing is the state of our mind and heart, the inner altar that is also the home of God.
