So the stimulus or experience is nothing?
What is nothing?
Humans create meaning. And with that meaning we invent words like nothing. And words like all these I'm writing now. Outside of human consciousness, do any of this exist? Is the English language the language of the universe?
Behind everything there is just... Whatever it is. And whatever it is cannot be explained because to explain it would mean to attach meaning to whatever it is which means we are now no longer being objective in and impartial in our assessment. We are projecting and so we fail in even coming close to describing what exists beyond the manifestations of human consciousness. And we can't be any objective because naturally as humans we are biased towards our experience and we cannot see outside of that experience to differentiate and objectify.
Our closest explanation of life without humanity is nothingness. Without humans there wouldn't be the chatter humans make and the external manifestations of this chatter turned into expressions of our experience ie the world we have created around us. The Earth would be undisturbed and the natural order of things would remain unaffected. There would be no laws, no rules, no borders, no politics, no economy, no debt, nothing. There would be no meaning in anything because we are the only animals to emphasize meaning because we are meaning making machines because of our unique level of consciousness that affords us capacities no other animal is known to possess.
Which leads back to the original point. If there's no humans to create meaning, is there really meaning to anything at all? That answer is pretty obvious.
Its not a bad thing though. Why does life have to have meaning? And what exactly do we mean by meaning anyway? For most people their ideas of meaning are actually meaningless because they are unaware of what their life means to them anyway beyond the myriad external influences in the world we have created to manipulate, influence and nudge them to particular outcomes to serve particular goals socially, politically, economically, financially etc.
What DOES life mean? Most people can't answer that question anyway and so what are they missing out on? Judging by the direction we are going in in the West, meaning has been lost anyway. People aimlessly going through life consuming, pushed and pulled like puppets on strings, neurotic and impulsive experiencing rollercoaster emotionality and states of wellbeing, stressed and inherently insecure and isolated spiritually, emotionally, mentally etc. We all have the wisdom that is inherent within us all that understands the cosmic game that is going on. The fact that really its all a big game the universe is playing and that it actually means nothing at all. Here we are experiencing this unique once in a lifetime thing we call life and yet we have little control over the rules of the game. We like to think we do but we don't. And therein lies the problem, IMO anyway.
Because we cannot control life, and because then we attempt therefore to control it obsessively, we actually lose control even more of something we can never possess anyway. We want to be the victors over life and dominate life into submission but life plays by its own rules and those rules are what makes the fabric of our reality and all of existence itself and its something far more than we ever will be. We all know this anyway when we appreciate the power and beauty of nature. There is something beyond us that we acknowledge exists that is awe inspiring and wonderful but we also acknowledge we are subordinate to it. And when we attempt to control nature and control the universe, we inevitably suffer the consequences as we see in the world around us and the destruction we cause/are causing as a result of our desire to attempt to severe our connection to our human condition and the relationship we have with this world.
Its all about control. However as Buddhism teaches, and other religions and spiritual teachings too, it is our attachment to these beliefs, actions, intentions and thoughts that corrupt us. The more we cling, the more we suffer.
