Well the book that I was told was THE WORD OF GOD and all that, it's like... people wanna list rules that we can all follow with our heads and say "this is always right in all situations" and "this is always wrong in all situatios". But I have broken free from that opinion, and it's not me caving to something I don't feel no this is like... a hunch I've always had that is now being confirmed by experience. And it's not the relativist notion of "there is no true right or wrong" oh no I think there is, but I think it can't be decided by a list of rules. It's like a wavelength, it's like a light wave, it's an energy you either ride or you don't, and it's fluid toward specific situations you know what I mean? So what might be the right choice in situation A) is the wrong choice in situation B) etc. So how do we cultivate it? Yeah like you said, you gotta start letting the divine show you until you yourself begin to think like the divine.... And yeah, Tarot is definitely a phenomenal tool to add to the kit!
Ah but I'm sure you know that there is judgement, the one that bothers us all and which causes so much trouble like you've observed and which made you go extreme, and then there's "righteous judgement" (I assume this means judging from the standpoint of the divine). The Tarot can contribute to our cultivating this. It won't do the whole job, but it can be a nice room to add to the house.
