is buddhism outside the idealism and materialism? is buddhism is not certainly the idealism or materialisn?Buddhism philosophy is about the consequence mechanism about five elements* and those elements aren't viewed as the material,antimatter or spirit.But the motion and change of them is showing that Buddha or at least the nearest original of his book want to say that the motion and objective reality(material or time) is real,and it sounds like materialism.But the motion is come from,where?isn't it an conscious,thinking of mind construct from data,to create the motion,the time concept and feeling about it?Some time buddhism mention about mind,but doesn't it say the mind is a part of motion of elements?* fundamental elements (vietnamese: ngũ uẩn)
Buddhism points out that both are concepts, reality is free of concepts (unless we impose them).

In my experience concepts like idealism etc. are deeply ingrained, unlike "my nose is itchy", so it's useful to remember they're just in my head.
