Not that Nietzsche is necessarily the right voice on a Buddhist forum, but he reflected wisely I think on the question of the ‘true world’, or ‘ultimate reality’. Maybe also interesting for @Brother_Joe. Here a quote from “Twilight of Idols”
HOW THE “TRUE WORLD” FINALLY BECAME A FABLE. The History of an Error
- The true world–attainable for the sage, the pious, the virtuous man; he lives in it, he is it.
(The oldest form of the idea, relatively sensible, simple, and persuasive. A circumlocution for the sentence, “I, Plato, am the truth.”)- The true world–unattainable for now, but promised for the sage, the pious, the virtuous man (“for the sinner who repents”).
(Progress of the idea: it becomes more subtle, insidious, incomprehensible–it becomes female [comment: let’s ignore the misogyny for now] , it becomes Christian. )- The true world–unattainable, indemonstrable, unpromisable; but the very thought of it–a consolation, an obligation, an imperative.
(At bottom, the old sun, but seen through mist and skepticism. The idea has become elusive, pale, Nordic, Königsbergian [comment: i.e. Kant].)- The true world–unattainable? At any rate, unattained. And being unattained, also unknown. Consequently, not consoling, redeeming, or obligating: how could something unknown obligate us?
(Gray morning. The first yawn of reason. The cockcrow of positivism.)- The “true” world–an idea which is no longer good for anything, not even obligating–an idea which has become useless and superfluous–consequently, a refuted idea: let us abolish it!
(Bright day; breakfast; return of bon sens and cheerfulness; Plato’s embarrassed blush; pandemonium of all free spirits.)- The true world–we have abolished. What world has remained? The apparent one perhaps? But no! With the true world we have also abolished the apparent one.
