My speech to a 50 year HS reunion would ask, "At the time of our graduation, who among us in our wildest dreams, our deepest desires, our plans, projections, expectations, intentions, etc. was thinking that my life 50 years from now will be just as it is now."

Those who answer affirmatively may be among the saints and sages who know now that 'it is just as it is' whether we believe, understand, grok or deny such objectivity.

Things happen! For those seeking certainties and explanations for everything, I suggest the 'Ultimate Conspiracy Theory', the greatest of all creative speculation, Advaita Vedanta.
Everything is an inside job and "you're it".
