Everything is subjective, because if you take away the observer, noting exists at all. Truth itself never changes, though that which it illumines may change. Light illumines red today, green tomorrow, blue the day after. But the light does not change. Same way - truth shines in all ephemeral things, but we take the things to be true, rather than the truth itself, which is the substratum of all things.
honestly, i think everything is like a spray of waves and molicules, but our eyes took the fuzz out of it all and tried to make sense... when all of theis is just heat and waves.
You are right, but you are also not right, just because a wooden chair is made of manly organic molecules and I am made of molecules does not mean there is no difference between the chair and me. there is a difference... and this is at one level. Similarly, everything is heat and waves but thats at one level, at the other level we have so much diversity... so what is the truth? both are and you cannot neglect either.
