> changing how you in particular perceive the world does not actually change the world that you are a part of
It's impossible to change yourself without changing the world, because those two things are not separate.
Further, much of the world exists only as abstract ideas in my mind. When I change how I relate to and perceive them, I do change them in every way that matters.
If by "you" you mean the totality of the universe that you are a part of, then changing "your" consciousness does change the world, but if you think of yourself as merely an individual subject--not a subject as substance--then nothing you do to "yourself" will lead to liberation, because others inability to find liberation creates a contradiction within your own.
Sure, if you discount the fact that other people exist, are conscious, have their own experiences of the same world and also experience joy, sadness, love, and suffering.
To assert that your perspective is the only thing that matters is to assert that nobody else matters.
its a matter of perspective. if everyone is one, no one indeed matters, nor exists. This is not discounting anyone nor any fact. what does not exist cannot be discounted.
