In the pre-modern past, meditation was a matter of getting past the surface illusions of the mundane world; and re-connecting with the reality beneath. In other words, ancient meditation enabled Man to pierce illusion and discover The World, as it truly was.
Past meditation was therefore a negative method - a matter of removing, of discarding; yet it had positive results, because reality was already there, behind the illusions, 'waiting' to be discovered.
This was possible, because pre-modern Man retained a connection with spiritual reality; and it was this underlying spiritual reality that provide the consensus view of Mankind. It was indeed a 'common sense' because it was common to all Men - and meditation was able to discover this unifying commonality below the variable surface of personality and custom.
Remove the illusions of the merely personal and local; and the eternal verities remained.
But modern Man is cut-off-from the spiritual, is alienated from the common world. Having become a detached individual; modern Man has lost the spontaneous and unconscious group cohesion; a product of immersion in the spiritual and divine - which remained, until recent generations, as a dwindling residue of Man's earliest consciousness.
Nowadays, when meditation strips-away or dissolves the surface illusions of the world - nothing remains.
When illusions are cast aside - there is nothing left! When a negative method of meditation is deployed the outcome is itself negative; because there is no 'consensus reality' waiting to be discovered - but instead a void.
By meditation, modern Man does not gain the world, but loses it.
While pre-modern meditation (in the right context) led to a strength and encouragement rooted in solid reality; modern meditation leads to nihilism and despair... If, that is, modern meditation is pursued rigorously and honestly.
But it is not! Since modern meditation leads to no values, not motivations, and loss of the world; then, meditation is almost never pursued to its logical conclusion.
Instead, modern meditators use meditation as (merely) a therapy - directed at making the meditator feel better. And as such, modern meditation is embedded in the standard, mainstream, totalitarian-leftist assumptions of the modern world - hence, modern meditators attitudes are worldly, contemporary - and labile in accordance with tracking the changing and rootless dictates of the global Establishment.
Consider: If modern meditators were genuinely committed to the idea that everything was one, the world was illusion and the self/ ego and thinking were the cause of illusion - they would realize that this illusory nature extended to all of morality.
They would reject all notions of human rights and equality, because these are part of this world's illusion; they would realize that kindness was as illusory as aggression; that suffering was as illusory as the political views of their enemies.
But this does not happen. Meditators claim that oneness meditation has all sorts of this-worldly benefits. Some claim that an increase in meditation, or many meditators working together, will improve our lives in this world. Or that meditating makes for better people - kinder, more appreciative, more altruistic people!
Because this is incoherent nonsense; in practice modern meditation that aims at seeing through the illusion of this-world is itself worldly - hence just-a-therapy, at best. It does not have the potential for transformative religious or spiritual power.
I agree with the view that some kind of 'meditation' is valuable, and for some people necessary, in this modern world; but its aims need to be quite different from the merely negative goals of seeing-through illusion - almost the opposite.
Modern meditation needs to be - not about 'discovering' a reality already there - but instead about co-creating a reality that we choose and is in harmony with divine creation.
We, as selves, need to start working with God in choosing to make the reality - which will not happen unless we take an active and conscious role.
And that should be the nature, method, goal of meditation in 2023.
