We have been given the means to remember Heaven. It is the vision the God Self holds for us and comes to us thru the practice of forgiveness. It is simple and direct and unfolds in this way: There is no sin in Heaven for there is no desire not to Love. Outside our story of the world, there is no sin in our brother. In him is Heaven. But when you see sin in him the Vision of Heaven is lost. Forgive him. Free him of your guilty projections. Ask your God Self to see and embrace your connection to him and in your joining with him will the awareness of Heaven return to both of you.
