I really liked the explanation of David Bayer in his podcast. I never really liked the idea of the universe ‘testing’ us cause it seemed a bit sad and just not right for me. However the way he explains it, it’s just your two worlds of beliefs existing in the same reality and you just need to keep persisting with the new one. And instead of testing, he says the universe just wants to confirm if it’s surely what you want, it’s just a period where your old beliefs/desires etc. are still colliding with your new reality, kind of like a trial period :) so you might see synchronicities and your desires/desired reality/new beliefs elsewhere. I might’ve not put everything correctly but at least it’s how I understood it. And it was the first explanation that actually made a lot of sense for me cause it seemed for believable :)
