But this isn't a linguistics thread...and I'm afraid the mods will lock it if we continue to discuss things other than what the thread is about.
Those sneaky mods! Actually, we aren't
quite that rigid.
Hmm...one universal source, which begets 2 primal opposites, which further breaks apart into 5 elements. Then you have the seasonal ceremonies, probably based on astronomical times... Sounds a lot like hermetics to me, although you'll see traces of this in taoism (the one source & yin/yang), yoga (earth, air, water, fire, ether/light), wicca and various other religions. The chinese have 5 elements as well, but they differ: fire, water, earth, wood, and metal. Those just never made sense to me, but it could be just a cultural difference. Have you done any reading/research into hermetics?
I think all religions have similarities when it comes to general concepts/ceremonies etc. Probably because they all tended to borrow certain things from each other. Just my opinion...
I wonder if it's okay to follow my own religion. I've been doing so for years and I found out it's one of the things that makes me truly happy. In practice, I'm really just what I'd call an agnostic, but I'm waiting to convert to my own religion once I've finetuned everything
If you've been following it for years, then what do you need to do "to convert"? It sounds to me like you're already committed. What else is there?
Is it wrong to believe in this? Is it wrong to educate others about it, in case they're interested in it as well?
I hate getting into the topic of right vs wrong. The buddhists have a saying: There is no right or wrong. There is only what you do.
As far as I'm concerned, if you aren't harming anyone else with your beliefs (physically or emotionally), then you are free to follow whatever path you choose. If you doubt what you are doing is right for you, then perhaps you need to think further before committing yourself to this.
I'm curious. I was once called "schizophrenic" for following this path. I'm tired of persecution and intolerance. I want my religion to be real too, because it's very real to me.
If its real to you, then its real. Having it be 'real' to others is irrelevant. It doesn't matter what others think/believe. Doing what makes you feel fulfilled is the right thing to do for you. Unless, of course, feeling fulfilled means sacrificing virgins or something...then you need more help that we can provide!

One last comment, why do you feel the need to advertise, for lack of a better word, your religion? Does it matter if others know about it? You've found your own path, which is great. Most muddle through life following society's expectations, never really feeling fulfilled or happy spiritually. If people ask you about it, then go ahead and share it with them. But I would question your motives for 'starting your own religion', even if you call it an 'order'. Does the idea of followers appeal to you? Are you more comfortable practicing this if you feel you aren't alone in doing so? Personally, I would worry less about how to get the word out and focus more on why you want to get the word out. I think you'll find out more about yourself you do so.
