Absolute Reality vs. Relative Reality

I'm just doing my best to understand all this so I write it down.

In the Advaita understanding there is only one Absolute Truth and that is the fact that 'I exist'. Everything else is unverifiable. How do I know you really exist or that this computer really exists if in our dream state we can fabricate these things and these events. When you're sleeping and dreaming if you want a purple forest, bing! There it is, if you want tea with a friend, Bing! there it is. So I can't know with absolute certainty if what I'm doing in any given moment is a dream, but I CAN know that there is an 'I', and that's the only verifiable truth. This is also called Solipsism.

Then there is the reality that all of us share here, relative reality or consensual reality. We agree that this is a tree and that is a rock and that we are having lunch or whatever. This is the reality that the body, mind and ego inhabit and must contend with on a daily basis. When the body is hungry, we eat, when we're driving, we pay attention, when we're tired, we sleep. This is also the place where we are the product of our upbringing, we contend with our emotions. If we were trained to face each new task with fear, then at some point, if we want to show up in a different way for life, we must contend with that, look at it, observe the mind's and body's reactions to stimuli and overcome that programming.

There is work to do within relative reality and that work has outcomes. Achievements occur. We use the mind as a tool to unravel ways of thinking that limit our ability to fully experience life or to experience it with a broader range of emotional response.
