Wow this thread's awesome. Love the replies here, I'm learning heaps.
I'll offer my perspective on this to hopefully clear up any confusion (mostly for my own benefit too, hehe).
I loved that leaf/tree example by ethereal, btw.
SecretSeven, just think about this world here, like you would a dream at night. That's basically how I explain subjective reality to myself. If you saw another person in a dream, what would you think? They aren't a seperate person, with their own consciousness. They're just in your head, just as much as the "body" you're "walking" around in (which is also just a part of your imagination). I'm talking about a dream in this example.
So how do you know that right now, this isn't all in your head? That all the posts here, all the people writing them, Steve, his posts, the leaves on the trees outside, the breeze hitting them, time/space, everything... is all part of your consciousness, like it would be in a dream? When I say "in your head" btw, I'm not referring to you, SecretSeven, your ego's head. The person you're consciousness is sitting in right now... that's just a person, just like me, like ethereal, like Shindra, like everyone else (and everyTHING else). We're all, you included, leaves on the tree. Subjective reality is simply letting go of identifying yourself as SecretSeven, and all of us as seperate beings from you... and embracing the "dream", and saying that, like in a dream, you are really everything that exists, equally. So you're not just SecretSeven, you're him, and me, and Shindra, and ethereal, and this thread, and the computer, and Steve, and the mountains outside, and the clouds in the sky.
Hope that helps. I'm also just beginning to understand, and haven't completely accepted it as a default perspective.
Ciao!
