I was just reading A Thousand Names for Joy, and I thought of you & this thread as I read Chapter 77. I don't have time to excerpt it here, but she makes the point that it's our thoughts about things that create the problem, not the things themselves.
I look at myself, and my ability to be stable despite losing everything, and the picture I get is: where is my anchor? Where am I anchored? If I'm anchored in what I'm calling my life: my work, my kids, my play, my stuff... then I will be blown about if a storm takes those things away. If I'm anchored in my own heart, in my deepest, most expansive self, then nothing can shake me. I will always have me... until I don't have me anymore, then I'll return to source, which is probably also an illusion!
Eventually, all things merge into one... and a river runs through it.
