Agree. it’s all conjecture and opinion, or let us say ”waffle”.
As soon as you make one undisprovable assertion e.g. ”invisible unicorns” or ”eternal soul” you have to build a complex cosmology for all the questions it raises. The vedantins love it. Pundits, scholars, gurus, acharyas, swamis and teachers (I include the BK & PBK organisations in this) can waffle and extrapolate endlessly, sounding clever, building narratives which affect people looking for "answers".
Until the cows come home, they speculate and rationalise their speculations of other lifetimes, other ”lokas”, ”higher frequencies”, theories of karmic accounts and akashic records, ascended masters - a giant carrot dangling in front of gullible donkeys to distract from the here and now and extract/transfer energy from those donkeys to the cart it is hitched to. All because the ego finds it hard to accept itself as fallible, transient, that one day it will not exist. Soothe the insecure immature ego-child with a story, who spends its energy every day rebuilding the make-believe story world with mental affirmations and ‘rituals’, hoping one day to step through a magic portal to inhabit it ”for real”.
I remember in kindergarten we had a regular time for free play. I remember that for a long time, many weeks, a friend and I would play with wooden blocks, large ones, and each day we wanted to play a particular game in a fantasy where we would build a boat, based on some TV adventure show, and be the characters in that story.
The thing was, every single day, the free time would end before we had finished building the boat, the fort and the rest of our imaginary adventure world. We’d try harder each day to build it quicker so we could actually play out our fantasy game. And we did get quicker from the regular "rehearsals” but we never once got to enter the fantasy world fully to actually play the characters of our game in a completed "set”. We eventually switched to other activities.
Occasionally a "spiritual teacher” will have learnt some variation of what really is primal shamanic techniques and call it ”meditation”, badged as their trademarked technique. They’ll set up a structure to propagate it and sustain themselves physically, and egoistically. Not saying they don’t believe it sincerely, you have to believe it sincerely to be able to enter the ”virtual reality” world.
Play is healthy. Being childlike in play is therapeutic, refreshing, rejuvenating. That is different to being childish or being infantilised, losing one’s autonomy as a free-thinking adult wanting to believe in ‘desirable' speculations.
Mental gymnastics, imagining different "as if” scenarios, can be immensely beneficial, it's why we love movies and stories and role playing for fun (or need it as therapy!). But let’s keep perspective and check the fundament of what’s going on, what is real and what is imaginary, what is actual and what is placebo.
Forget about what people say they are meditating on or believing. What they are really meditating on, what they really believe is revealed in what they create here and now around them. This is many people in the world BTW, not just BKs and their ilk.
