Since it has penetrated, and dominates, almost everywhere in the realm of finance, the media, economics, politics, the military and police, law, religion, science, arts, health etc; it is easy to regard The System as a physical entity only; and to neglect that The System has also come to replace the spiritual by a simulacrum.
In other words; for most people The System provides their only escape from alienation - their only sense of belonging, connection, participation in the world around them.
This is one deep reason why the masses will believe whatever The System is currently telling them - no matter how incoherent, vile and inverted; because only by joining-in with today's-frenzy of communications can they escape their profound existential isolation and feel a part of the world, the community.
Of course; it is only a very partial and temporary alleviation; but that fact merely fuels the addictive dependency - and explains why social media have become integral to life for so many.
What we are instead supposed to be doing is consciously to participate in the world of God, angels, spirits, and other Men's 'divine-minds' by voluntary and chosen acts of our individual consciousness.
Then; individual men may know directly and by personal experience the wider world outside their own minds.
But for this to happen, we must (first) believe that such a world is real and accessible - and not merely a delusion, a manipulation, or wishful thinking.
We must also have realistic expectations of 'what it is like' to access such a world; in particular setting aside any fantasies or hopes of reversion to a prehistoric/ primitive/ tribal (or early childhood state) of passive and unconscious immersion in the group mind.
We also need to eschew any covert hope that such access will bring us personal power, statsu or other kind of success; and also forget any notions that we can (or should try to) convince other people about what we discover in such experiences.
The essence of what is possible (and desirable) is that each needs to do it for himself.
These are, I believe, the only two possibilities: Either we accept The System as 'our god' and salvation from the existential horror of alienation; or else, we decide to reconnect with the wider world by means of our chosen conscious thinking activity.
By The System we are densely-connected - but any connection is indirect (via language, image, symbol - which must be interpreted).
But by the deployment of our chosen conscious activity, we dwell in the wider world of Beings directly and unmediated - we may live-in that spiritual world, for a while.
