This understanding awakens in me and I can measure it. If it becomes increasingly clearer to me that only in our common, single desire will we all reveal the Light that Reforms, the Creator, unity, and the end of correction; if I feel that this is so with my whole being, that means I advance.
You can almost check it using a ruler. That’s how clear-cut everything is in this endeavor.
