The Course makes no claim to finality, nor are the Workbook lessons intended to bring the student's learning to completion. At the end, the reader is left in the hands of his or her own Internal Teacher, Who will direct all subsequent learning as He sees fit. No more specific lessons are assigned, for there is no more need of them. This is how the Course in Miracles begins. Knowledge is truth, under one law, the law of love or God.
Truth is unalterable, eternal and unambiguous.
It can be unrecognized, but it cannot be changed. It applies to everything that God created, and only what he created is real. It is beyond learning because it is beyond time and process. It merely is. The world of perception, on the other hand, is the world of time, of change, of beginnings and endings.
