As above so below.  Your universe is on a grand cyclical trajectory, expanding as it goes.  Why do you speak of expanding your knowledge?  For that is what happens as you go through life.  That is what happens to all extensions of Consciousness as they travel the cyclical journeys of existence.  Your lives are cyclical.  You expand as your make the ever-onward, ever-upward journeys.  Are you growing?  Physically, of course.  The question is, are you growing in alignment with the Source of All That Is?  What do you think are the essential qualities of a Creative Intelligence from which arose mountains, oceans, stars, and you?  Be the embodiment of these qualities and you will be right on track in your journey.  You are so very loved.
