So awesome that you started listening to Passio! He is honestly one of the best teachers I have ever had. He will take you really far down the rabbit hole... haha so be prepared. The quality of the audio gets better after 20 or so if I remember correctly. I think I mentioned it before but I went through all his material and it took me almost two years because he has so much of it. But I had to take some breaks because it did start affecting me emotionally. but after a week or so I was good again to keep drinking from the fire hose lol.
Yeah solipsism is people being their own arbiters of truth and anything outside of their own mind is unknowable. Seems to conflict pretty strongly with those who value objectivity reality and objective truth. I think his position on solipsism makes sense. I agree with the vast majority of his work, but there are a few things I don't. Not much.. but there are a thing or two.
Overall, the biggest things that I learned was how much I still had to learn so it was very exciting to get introduced to a lot of these topics and then you can do deep dives on the things you want to learn the most about.
Likewise, soul that is currently occupying "Ken's" vessel :) You cracked me up with that, but you are totally correct!
