This is something that I found is not fruitful to bring up in an "environment" like this. At a young age I had some experiences that lead me to the conclusion that words are just not good enough of a tool to base an exploration of this kind. Sure words help, but only when they are spoken with authority. And I don't mean some BS "title authority" (priest, judge...) but the authority of lived experience. If there is no eye to eye connection I am not comfortable with (for the vast majority of the cases) vaste my time typing symbols and falling into a trap of broken phone. What one word means to me can mean very little or just plain different to other person. Words (language) can be used as tool for conceiving the obvious and I believe that the story of The Tower of Babel is expressing that. If truth is wilfully distorted the languages, codes and top down authority imidiatly emerges. In that phase it is already too late as the whole structure is build on lies governed by brute force. I can see this clearly and could express better in my native South Slavic language. I have written lots about it for myself, but unfortunately I can not translate it easily into English.
I guess that this is a very long way to state that I don't want to talk about this kind of topics if a person is not in my presence. I can get much more from observing other person for a minute than from reading a book of some stranger (not that I don't read).
But in essence, my best guide would be the person that I see is living what he is "preaching". Or at least that he is doing his very best in that direction. I can detect lies pretty well and if I detect a true lie even once the person is disqualified regarding "this matters". So there are few essential criteria, like honesty, speaking truthfully
, behaving in accordance (not rigid just in harmony)...and then I am open. But I am not expecting to find that online.
Edit - I don't want to insult kind, sincere and knowledgeable people that are interacting with me online. Just wanted to state that I am not comfortable with discussing such essential matters online, not that there are no people who I would have high regards and are discussing this matters online. Now you can see why I dont like communicating via words only.
