Judo is a perfect example of how too much daydreaming lacks any real-world footing. In about 90% of scenarios, it looks like a master is just going to get overpowered by some average linebacker from Ohio. When you look at actual police work, the only version that works is the most physical one—the kind with the least amount of energy-philosophical mumbo jumbo.
1 - Did you maintain a barrier between your palms to block heat transfer and air movement? Also, was the blindfold tight enough to ensure that light and shadow patterns couldn't interfere, even if shapes weren't visible?
If you didn't start this for nothing, then:
2 - Was this exercise performed on a statistically significant sample size? Did you conduct an independent analysis to prove the success rate is actually higher than mere chance?
If you didn't start this for nothing, then:
3 - Have you allowed other groups to replicate the experiment using identical or even stricter criteria? Have you let people trained in rigorous scientific methodology test your process (I'm just wondering what else might be skewing the data here)?
If you didn't start this for nothing, the results are still just indicative and inconclusive;
4 - Have you run other experiments to rule out alternative explanations? You need to establish that an energy model is truly what best describes and predicts these events, rather than something like telepathy, field effects, quantum non-locality, or just some kid presenting his own symbolism through the guise of "energy."
If you didn't start this for nothing, you haven't confirmed a theoretical model yet. You've potentially identified an occurrence that falls outside the materialist-reductionist framework, but you certainly haven't defined a new one.
casualtiger2 said:I can't even remember when I first tried this—or why, really. Either way, there was zero hypnosis involved, and nobody was feeding me suggestions about what I should be feeling (which is why I didn't claim any massive sensations were possible in the first place). But, looking at how things work in spiritual circles, you’ve got people who haven't even tried it yet but already have an opinion—some cling to theories, while others see nothing but demons (or just assume it's all hypnosis/suggestion). The practice doesn't need to be long; we aren't talking about exhaustion or hand cramping, nor is this some attempt to "clench hands" (?). Anyway, here’s my take—after about 10 to 30 seconds, I start feeling these "ants" crawling through my fingertips and the center of my palms, along with a distinct flow of "energy." In the middle of my palms, there's also this extra heat (if you've ever done Yoga Nidra involving conscious awareness shifting, or maybe some Autogenic Training, then you know the drill—wherever you focus your attention, that part of the body gets warmer, more relaxed, or "heavier"). After a few minutes, an "energy" flow establishes itself between my palms; when I slowly pull my hands apart, it feels like they're connected by some kind of elastic band. That connection usually snaps and vanishes at around 15 or 20 inches. PS Elizabeth Castillo87, we're talking about etheric "energies" here. Does our discussion actually serve a purpose? Thomas Nelson25 Do you practice Judo? I experienced some "incredible" things regarding ki flow back then.
Suggestion doesn't work in such a banal way. Nobody has to tell you "do this and that" directly; in fact, that can often be undesirable. A huge part of the process, especially in modern hypnosis, is indirect.
For instance, the mere context you provided creates an expectation for a certain category of results. Because of its openness and non-authoritarian nature, this is often a more effective suggestion than direct commands, which can trigger resistance in people who dislike authority, leading to a counter-effect. If I wanted to induce one specific way of experiencing "energy," I wouldn't use an authoritative command; instead, I’d use indirect methods, like preparing the ground with an introductory lecture that mentions someone else's experience. You aren't imposing anything on the person in front of you; you're just creating a specific expectation. But since everyone is different, it's more profitable to work with a group—if you want as many people as possible to experience something, you keep the possibilities wide open.
You don't even have to try. Just relax completely in that position and your fingers will naturally curl inward; it's just how tissue structure and gravity work. Keeping them straight essentially creates tension against the natural direction of movement.
Speaking of Autogenic Training producing similar effects—that is pure suggestion, derived from hypnosis. Even Yoga Nidra, in the form we know today, is a modern invention, likely developed within Western yoga schools. While theoretically linked to ancient Upanishadic claims, it was probably adapted from Western practices like progressive relaxation, AT, hypnosis, and similar techniques.
casualtiger2 said:Has anyone actually given what I suggested a shot?
Not right now, but I’ve definitely dabbled in plenty of similar stuff over the years. I’ve messed around with bioenergy nonsense, Reiki, Chi Gong, those little energy balls, and all that. I honestly thought I was feeling some kind of force. That was before I got a better handle on psychology and gave hypnosis a shot.
Looking back with everything I know now, the whole energy hypothesis feels significantly weaker than this other theory.🙂
Maybe try suggestion, perhaps paired with some physical mechanics (for instance, how shifting into an unstable posture with tucked legs during rocking or swaying makes it easier, especially with eyes closed. I'm not sure if we can speculate on things beyond just pure suggestion here, but I'm just noting the theoretical possibilities)*.
It’s incredibly easy to trigger various physical sensations—tingling, warmth, "energy (which doesn't actually mean anything; it's just a nonsense label for everything and anything)," "magnetic attraction," and so on—simply through suggestion. It's much easier to pull off than full-blown hallucinations, though those are certainly possible too.
*Roughly speaking, relaxed fingers tend to curl slightly, particularly when held upright since gravity pulls them down. Holding palms flat creates a specific forward and downward pressure toward the other palm, which can create an illusion of attraction. Proximity alone is also enough to transfer body heat. These little details work wonders when combined with suggestion because they kickstart a feedback loop of self-affirmation. Once you start feeling *something*, you begin to "believe," which makes you more suggestible. Then, suggestions that aren't even directly related hit harder, further reinforcing that belief and suggestion in a continuous cycle. One of the core principles of suggestion and hypnosis is creating these little lies to progressively ramp up suggestibility.
casualtiger2 said:Theoretically, there isn't just one aura—there are several (etheric, astral, mental, etc.). At every level, we have a corresponding body that allows us to interact within that realm. Some parts overlap with the physical, while others extend outward—which is why that stuff extending beyond the physical, the part that’s easier to notice, is usually called the aura. Think of it like the corona around the Sun. As for the etheric body, they say it extends anywhere from a few centimeters up to about a foot (while the astral and mental auras have an even larger "reach"), depending on the person and their psycho-physical state. Apparently, your ET state is huge for your overall health.
It would be pretty interesting if everyone interested gave a simple experiment a shot. Put your hands together like you're praying, but don't actually let your palms or fingers touch. Keep the fingers slightly curved and a few inches apart (on each hand individually, and away from the fingers of the other hand). Roughly like this (+ spread your fingers out), but without contact (PS: imagine you're holding something, like a vase). Try to focus on the flow of energy through your fingertips and the center of your palms. Does anything happen? (Try it a few times, for at least a few minutes, staying completely physically relaxed but mentally focused).
They run tests like that all the time at circus hypnosis shows to measure suggestibility. There’s no such thing as "energy" here. 😉
In spiritual circles, people love tossing that term around to give abstract feelings or theoretical ideas an air of scientific legitimacy. But based on what we actually know right now, that "energy" isn't really there in a literal sense.
That doesn't mean nothing is happening. It just means that using the concept of "energy" is likely just our way of translating complex experiences into symbols our minds can grasp. It’s no different than how a shaman might interpret those same intuitive, psychological, or physiological sensations through the lens of nature spirits or ancestors.
David Vaughn75 said:People always get happiness mixed up with pleasure.
Pleasure can be anything from some cheap thrill to high-end luxury, but let's be real—it's just material stuff that disappears the second you stop touching it.
Exactly. That’s why they spin these fairy tales about eternal, transcendent happiness—it's basically just an antidepressant disguised as hope.😁
As far as my role as a moderator goes, I haven't received any reports on that thread, nor have I personally read through it, so I definitely didn't moderate anything. Unless I’ve suddenly developed some serious memory loss 😬
So, either nothing was deleted, someone else handled it, or we're looking at a technical glitch 🤷
Ryan Wilson2 said:Good grief, bluemason3, are you practicing your stump speech for a run for Congress or something? 😁
Given everything that actually gets elected to Congress, you’d probably need to undergo some kind of cognitive decline—basically just stripping away logic in favor of pure, irrational nationalistic fervor. 😳
Historically speaking, this type of religiosity emerged when we transitioned from hunter-gatherer societies to nomadic and, eventually, settled agricultural ones. As centralized states began to rise, religion followed suit by becoming more centralized too. Once society shifted toward democratization and individualism, the religious landscape fractured along those same lines, giving rise to various movements often lumped together under the "New Age" umbrella. In that light, the modern urban trend of embracing paganism feels less like a return to roots and more like a romanticized, recontextualized spin—something much closer to New Age spirituality than the actual ancient paganism it claims to draw inspiration from.
No expert is a magician who can promise a total fix overnight. Most of them just have significantly more experience dealing with these patterns than the average person—who usually only knows their own specific case, which is both an advantage and a limitation.
Experience comes in all shapes and sizes. For the exact same diagnosis and medication, some people claim it completely turned their lives around, while others say it ruined them or made things worse. Even with two people facing anxiety and depression, the same antidepressant can trigger totally different reactions. For one person, it’s the solution they needed; for another, it might trigger mania or psychosis (though I don't want to cause unnecessary alarm, it's not exactly common).
Unfortunately, this stuff is just too complex to fully map out. It’s hard to get a perfect scan of everything, especially since most assessments are indirect, based on conversation and subjective feelings, along with a dozen other variables that could influence how a therapy works. At the end of the day, it often comes down to trial and error. A specialist just uses their knowledge and experience to statistically tip the scales toward a positive outcome. But just because one person had a bad experience doesn't mean we should generalize that or expect everyone else to react the same way.
In my opinion, things like hypnosis, Affirmations, visualization exercises, and relaxation techniques are essentially the same thing. Unless they’re wrapped up in some heavy market mysticism, they really just fall under the umbrella of psychology. Concepts like Transurfing or the Law of Attraction are just different Alternatives. NLP sits somewhere in the middle—it's built on psychological and psychotherapeutic models, but it lacks much empirical backing (though, to be fair, plenty of psychological models lack that too). It doesn't have objectively proven functionality that outperforms simpler methods of suggestion or persuasion; it's just that the need for commercialization and marketing drives people to inflate the complexity of these techniques and courses.
That’s not to knock psychotherapy, education, learning a motor skill, or even life experience—those are all forms of "subconscious programming." While any of this might seem miraculous to someone, I generally don't expect miracles from anything based on statistics, though I do expect some kind of relative effect from almost everything.
Gerald Hill said:Let’s be honest about the user posting as ''Unknown'': they are constantly spreading animosity toward religion, particularly Christianity. They do this through subtle implications, suggesting that religious individuals are inherently dangerous because they believe faith is built on malicious messages. Since Christianity is naturally the most frequent topic discussed on this subforum, these inappropriate comments serve only to incite hostility against a specific group of people. I could provide an endless stream of links to prove this happens frequently. While I am not a Christian myself, I find this constant posturing of moral superiority and supposed wisdom to be incredibly irritating.
Jeffrey Fisher5 said:Well, please—go ahead and find me anyone who would actually prefer someone unattractive, aged, and destitute...☕
@Maria Robinson2: One hundred is far too low—we should be talking about at least five hundred, provided we're dealing with a healthy twenty-year-old.
I certainly wouldn't object to the physique of a healthy twenty-year-old, though I would have some serious reservations regarding the consciousness—and the complete cessation of its further development.
That’s a tough one to untangle. Consciousness isn't some floating abstraction that exists independently of age—you can't ignore the hormonal, neurological, and biological realities that shape how someone thinks.

You really have to follow the threads and actually engage with them to understand the underlying motivations and why certain criticisms are being leveled; you need a certain level of intuition to distinguish between valid critique and the use of symbolic elements in metaphysics—elements that aren't explicitly explained because their whole purpose is to serve as a bridge toward deeper understanding.

To be honest, I find this—directed at a specific person—to be downright shameful.
Philosophy doesn't exist in a vacuum; it encompasses spirituality, art, politics, religion, history, and mythology... because it investigates the very roots of civilization and the ancient sources that stretch back to times when humans conveyed knowledge through symbolic language. To label the use of a cultural, spiritual, or philosophical symbol as "trolling" simply because it involves "mystification through cryptic suggestions" and doesn't offer immediate, blunt facts is, to put it mildly, a purely subjective interpretation. It results in narrowing the scope of philosophical discourse and shutting down the very auxiliary tools that are woven into the cradle of our civilization.
Issuing a red card for "trolling" is a disgraceful mark of misunderstanding, especially when applied here, given that I myself participated in the discussion and contributed significantly to reinforcing that exact symbolic detail—defending its credibility and the ancient wisdom that remains the subject of study for both modern scholars and classic philosophers—without allowing it to be belittled, and I was always very clear with my peers about where I stood; honestly, if we're handing out red cards for "trolling," I should probably be getting one too.
Having served as a moderator on the philosophy forum myself, I know exactly what trolling looks like; I’ve had my fill of trolling tactics used to obstruct and harass, and after all these years, I can easily tell the difference between genuine philosophical merit and total nonsense. There is plenty of nonsense out there, but true quality is rare.
The only reason I’ve stayed on this forum for twelve years, practically continuously (much like how Viviana used to stay), is because I love philosophy; but the truth is, as I become increasingly intolerant of stupidity and superficiality—which seem to be on the rise—I cannot remain indifferent. Philosophy is fundamentally a search for truth, so I react when I feel it's necessary, and I view this moderator intervention as an unobjective and shallow judgment characterized as mere trolling.
At the same time, though I suspect I might be the only active participant in this philosophy thread who actually feels this way, the idea that the majority opinion is somehow a valid argument has always been a total fallacy to me.
So, there’s absolutely no truth to this whole accusation of using "mystical, cryptic suggestions" to troll people. To frame it that way is just a complete misreading of my intentions, and frankly, it's just plain wrong.
Look, someone might not vibe with another person's style or how they communicate depending on the context—and trust me, I don't particularly love everyone's style either—but please, nobody needs to lecture me on what constitutes an "open, reasoned debate" or tell me I'm "stifling the flow of the topic" by "failing to say anything concrete." Honestly, that kind of thing is just pretentious and subjective; it's quite a leap to claim you alone get to define what counts as a "productive discussion" or what qualifies as "substantive," especially since there isn't one single, rigid template for how these things should go.
Just to be clear, I'm not looking to start a fight about any specific user, myself included, but rather I'm pointing out the issue with staying on topic—which is the only real way to stifle a conversation. We have rules about staying on track so that opening posts remain open, a rule that isn't really being followed lately, so we should probably pay more attention to that. My point is also about what a philosophy discussion should look like and what actually counts as a legitimate argument versus what doesn't (because you'd be surprised at the variety of "arguments" tossed around here, given that we've always had the freedom to argue however we see fit), all of which is being triggered by one totally unnecessary red card.
Nothing is truly mutually exclusive. Different fields naturally overlap, but they always approach things from their own unique angle. It’s the same with philosophy; someone might have their own take on art, but playing the guitar doesn't suddenly make you a philosopher. It only becomes philosophy once there's a conceptual framework behind it. When you’re defending a point here, you’re essentially trying to build an argument. We also have to remember that a forum is a specific kind of medium. We're limited to the written word, which means we lose all those subtle nuances you get in face-to-face conversation. Because of that, it's even more important to frame our arguments in a way that actually fits the medium.
If we aren't going to distinguish between different topics, then there’s really no point in having separate forums for religion, politics, spirituality, or anything else.

There are two ways people try to tell you that you’re clueless: the direct approach and the subtle one. The direct way is blunt. It’s the "you just don't get it" argument. It’s simple, aggressive, and usually lacks any real substance. Then there’s the implicit version. This is much more condescending. It’s when someone implies you aren't on their intellectual level, or they suggest you need to go study some ancient, obscure text before you dare to have an opinion. It’s basically a polite way of saying, "Go read a book and stop talking."You probably won't get it anyway. You lack that specific brand of esoteric knowledge I happen to hold—though I’m not actually going to say anything about it. I'll just leave it at an insinuation, if only to maintain a sense of pseudo-intellectual superiority in this debate.Those aren't valid arguments in any serious debate. It’s more like toddler-level communication.
I find it hard to accept any approach to philosophy that doesn't prioritize logic and formal debate. There needs to be at least a baseline level of discipline—staying on track and avoiding those tired logical fallacies. I’m talking about the usual suspects: leaning on authority, whether it’s your own, some ancient figure, or something transcendent, as well as playing on emotions. It's just a collection of propaganda tricks designed to bypass rational criticism so someone can pass off an ideology or a gut feeling as an objective fact.
Forrest Gump, acting as his defense attorney here—which, let’s be honest, violates the rules—isn't a new development. This guy has been hovering on the edge of trolling for a long time now; it’s just how he argues. Every other post of his is basically a wrapped gift that says: "You're an idiot who can't grasp the higher truth, so I won't bother providing a single concrete argument since you wouldn't understand it anyway." That kind of behavior wouldn't fly in any serious, coherent philosophical debate. Because he's been using these same destructive tactics for years, I've decided to start stepping in. I'm going to begin sanctioning this behavior to keep the discussions from falling apart.
I realize not everyone will agree with me here. My stance might be a bit too rigid, and sure, there’s room to let discussions breathe or debate how "philosophical" they should actually be. But this is the standard for moderation and discourse as I see it right now, and for the time being, I have to stick to it. Look, I don't have to be the ultimate arbiter of philosophy, and this isn't about me playing gatekeeper. That's not the issue. However, I can't sit by while deep discussion gets undermined and turned into aimless, low-effort chatter. At this stage, I won't tolerate personal attacks or trolling disguised as opinions that refuse to offer any actual substance. It just doesn't work for the quality of the conversation we're trying to maintain.
Historically, life expectancy was pretty low because people were constantly being taken out by infectious diseases and basic infections—things we can tackle pretty easily nowadays. I’m not convinced we’ve actually pushed past the physical limits of biological wear and tear; it just seems like more people are hitting those limits thanks to a healthcare system that clears the hurdles that used to kill us early. You might find one 120-year-old in a million in one area, maybe 100 in another, or perhaps even 50% in some specific group, but that doesn't mean lifespan is just going to spontaneously jump to 160.
On the flip side, there's a chance new research could actually crack the code on the aging process itself, which would be a whole different ballgame. We'll see. Though, honestly, I'm not sure if that's necessarily a good thing just because our primal instinct is wired for survival.
It’s hard to say for sure. If you look at the animal kingdom, everything has its pros and cons—different survival strategies just work differently depending on the environment. In some scenarios, a species wins by having fewer offspring, while in others, mass short-term reproduction is the way to go. There are plenty of combinations in between.
To put it simply, I think the biggest downside to a much longer lifespan would be how much slower evolutionary adaptation becomes when things change. It really comes down to how stable the social and physical environment stays, and how our cognitive abilities, ability to adapt, and skill-learning would hold up over a 500-year span. Of course, we'd also need to rethink how reproduction works entirely, since we're already dealing with overpopulation issues and an aging demographic in the US.
Taking everything into account, I suspect that just extending lifespans to such extreme lengths without making massive changes to everything else might actually cause more harm than good.
