What makes you think nobody has? Look at what @Mulberry posted for example… It’s not like sorcerers who have figured out immortality are going to get on Fox News and explain step by step how they achieved their state of immortality.
Telekinesis, and many other things are readily seen even on youtube these days. If you look at what monks can do, they train their bodies to do things many would think are impossible. That’s a fact.
If you truly believe that, I’m just confused as to where you believe this line is drawn in the sand. So nature doesn’t bar us from talking to spirits from another plane of existence, but it does keep us from immortality? As far as the time thing goes, I’ve actually been visited by my future self, so I have my own subjective proof that’s a real thing.
I’m not trying to bash you, but it is important to see our limiting beliefs for what they are because they are literally the only limits to what we can achieve with magic. Nothing stops you from communicating with spirits. We both agree on that. But there are people who believe that’s impossible, and thus it will be unless they change their beliefs. Same principle applies for the things that you right now believe are impossible to achieve. We overcome these limitations by destroying the limiting beliefs.
I hope you don’t think I’m picking on you personally. I just see these limiting beliefs all the time. Proclamations that we can’t do X no matter what. It’s stifling and dangerous to newer magicians who are still learning what magic is and isn’t. It takes a lot of effort to overcome programming and hindering beliefs. Many of us have had to destroy the JCI crap to move forward. I just don’t like seeing these limiting beliefs being spread as “facts”.
