Quote from A Course in Miracles Text Chapter 7 - THE GIFTS OF THE KINGDOM.

T-7.III.4. To be in the Kingdom is merely to focus your full attention on it. 2 As long as you believe you can attend to what is not true, you are accepting conflict as your choice. 3 Is it really a choice? 4 It seems to be, but seeming and reality are hardly the same. 5 You who are the Kingdom are not concerned with seeming. 6 Reality is yours because you are reality. 7 This is how having and being are ultimately reconciled, not in the Kingdom, but in your mind. 8 The altar there is the only reality. 9 The altar is perfectly clear in thought, because it is a reflection of perfect Thought. 10 Your right mind sees only brothers, because it sees only in its own light.
