The Buddhist philosophy is based on the eternal change in nature. How nature is changing itself on its own eternally is what it preaches more or less.
There’s also one other dimension, we can call it soul which is unchangeable, that is forming the foundation of the materialistic dimension of nature to evolve/change continuously. Nature in itself is complete is what the philosophy generally interpretes.
Now, some of us have doubts on when this creation called nature actually started. Well, it actually never started and will never end. Only the cyclic periods will start and end. Say a person, me, the cyclic period of me in a human form started the day I was born and it’ll end the day I will die or cease to exist. Like that, entire creation has it’s own cyclic period. It only ceases to exist in that particular form. We as apparent individuals together form the entirety of nature. Here, I say ‘apparent’ because our individuality depends on our interpretation.
Tomorrow, if we start believing the world to be our body then human consciousness will start believing it to be true in a while. And then you can apply the same logic on universe and even beyond that. That’s exactly why it is apparent. If you believe the world to be your body you will feel its pain much sharper after a while. You will start associating yourself with it with greater connection.
So this apparent belief that you are this body is what creates doubts or raises questions about the beginning of creation and so on.
Thus, according to Buddhist philosophy, the notion that nature is perfect is absolutely correct. The definition of perfection is again to be interpreted individually though.
I’d say, nature is neither good nor bad, neither material nor immaterial, it neither changes nor unchanges and that is exactly why it is absolutely perfect.
Om Shanti….?
