If you are with me so far; Man now has not just the capacity to imagine his reality - but he simply does, necessarily, imagine actual, current reality.
It is our fate and destiny that our reality Just Is imagined.
This was/ is the millennial change which was prophesied by some and felt by many more - albeit it has not worked out at all as the optimists supposed (those who felt a New Age approaching; which they supposed would be imposed-upon Mankind from the spiritual realm).
The optimists supposed that when Man imagined reality, Man would (they thought obviously) imagine a better reality... The problem was with what 'better' was supposed to be.
At first (late 19th, early 20th century) Man tried to imagine a 'utopia' in this mortal earthly life (a utopia perhaps including - what is not possible - immortality): a world without misery or suffering; a world of pleasure and stimulation.
But this was never possible - no plausible utopia was ever imagined, none were believed-in; and all attempts to do think or make utopia ended in dys-topia - which was a dominant popular art form from the later 20th century
(By contrast with utopia; believable imagined dystopias were ten-a-penny - and most of them have already come true - to some significant extent.)
By the millennium; Man had developed and decided-upon such an idea of 'better'; that it led to this trivial, bureaucratic, totalitarian world of incoherent and value-inverted ideology - a world of imaginatively-encouraged and officially-implemented resentment, fear and despair.
In particular Man made the primary decision to imagine No God - specifically that there was no God who was the creator, and our loving parent - with us God's children. For millennial Man; a better world meant first imagining a world without God; and that meant always dystopia (or one kind of another).
And having imaginatively ruled-out the reality of creation and the relevance of this world to each and every person - Man imagined a world of meaninglessness, purposelessness and isolation.
So far, so bad; but can we do better - starting from here?
The answer is Yes; so long as 'we' means our-personal-selves; and not collective humanity.
And so long as we do not repeat the mistake of trying to imagine a utopia in this mortal world - which is not made to be perfected; but was made as a (temporary) place of experience and learning to prepare us for eternal Heavenly life beyond biological death.
...Which does not-at-all mean that this mortal life is trivial -- on the contrary we are here, we remain alive (reading this, thinking about its implications) exactly because this temporary life is so important - forever.
What we imagine from here on, and with what motivation, is crucial - and by 'we' I mean you, and me. Since our life Just Is imagined; and since imagination (intuitive, from the heart's thinking) acts directly on creation.
Therefore I can think of nothing more important, immediately, than that we encourage and allow ourselves to imagine The Good.
The Good is that which is in harmony with divine purpose and 'methods'. Such is what we are here to learn and practice - albeit partially and intermittently - in face of many challenges and experiences.
