@Dosed,
What does 'knowing' consist of when we are speaking of sovereign beings with the capacity to make a infinite amount of expressions? with infinite potential?
Perspective and thought and experience are unique to all of us as free and sovereign beings. You may feel you know someone, as though you can predict their future implications, but the truth is, everyone has the capacity make a infinite amount of expressions, and those expressions don't have to meet up to your expectations and doesn't have to follow a path of rationality.
I agree with you, we are inherently alone, Dosed. Loneliness is a expression we all endure. Fortunately, we are in a separated state of finite mass and get to experience projections of other beings, who like us, are inherently alone, with the same infinite capacity of expression. As we go through life, our perspective, memory, and awareness changes and so our views on a subject change as well, and the way we feel about all things.
You can look at it in several ways, but I don't suggest beating yourself up over it. You can look at it as though the only reason our experiences cross is to create conflict, which very well may be true, or you can enjoy the experiences your going through, and continue to move forward in a positive light looking forward to the next cohesive experience with another, no matter how it turns out, or what they express, or what changes, because everything changes.
Experiences always involve positive and negative stimuli. Have you ever noticed that? It is by this we learn, and progress. You cannot fully know something without knowing its opposite, love/hate, light/dark, ect. Look at the whole picture.
With our uniqueness, we are all essentially loners. We have friends, companions, followers, and enemies, but at our core is a state of loneliness. The experience will continue however, your always faced with new propositions, someone to teach, and someone to learn from, and it all comes in the unique form of experience. I say enjoy it. Or not. Its really up to you.
