I accidentally converted myself to my religion, and now I've accidentally worked out how to word the description of my religion. I worship bringing the mind into harmony with Existence. The holy act is to think about Reality the way Reality thinks about herself. The holy ritual is to, second, genuinely speak one's thoughts. This latter turns out to be severally and surprisingly nontrivial.
Proselytizing is a sin. Rather than joining someone else's religion, it turns out finding your own has a simple recipe: imagine your ideal religion in detail. As much detail as possible: what are the buildings? The clothes? The processions? The decorations? If you do it correctly, you'll involuntarily convert yourself, the same way I did. It appears at first to be a fantasy construction, and it turns out to be discovery. You're hardly making anything up, instead you're finding out you already had a worship in there and it merely needs a opening so it can come out.
As with all holy things, while doing it correctly brings bountiful material boons, that's not the point. It is done for its own sake. Unifying thought and Reality is worth doing because it is inherently worthy. Truth maxxing for Veritas' sake.
