The central lesson of the Workbook, repeated in three separate lessons (94, 110, 162) and in every lesson of a twenty-lesson review (review VI). In essence it means that no matter what you think you have done, from the original separation at the dawn of time, through the seeming eons since, and throughout the entirety of this lifetime, you have not changed your original innocence, nor ever can. You still shine with the perfect innocence you had the moment you were born from the Mind of God, for you are still in that moment and always will be. Therefore, nothing is stopping you from going back home. Similar in meaning to "God's Son is guiltless" and "the separation never occurred" (T-6.II.10:7).
