As Hegel's dualism theory, there always will be two types of dichotomy everywhere. Like for good there exist bad, for optimistic there is pessimistic, for God there is Saitan, and the world forward is decided by the conflicts between this two. Hegel proposes that due to this conflicts the new stages or new theory emerges.

Now, if we keep this in our mind, how can we define truth? How it is ? And what is false? Everything becomes uncertain because according to Hegel theory with time everything changes.

If there is always a change going on resembles that what is truth now with time it won't be. And the false also does t always remains false. And this makes us to ask ourself what remains unchanged in our existential reference. 

Does that mean there is no truth that is valid for eternal? If so, what is truth?

Once I was surfing on a YouTube there I saw and interview of one Zen master and he defines truth as, " Truth are the truth and also those things which are not truth are also a truth".

According to him, everything is truth. Then, can't we say that,"if everything is truth , what's the point in defining it?"

if we going on searching truth at last we will be standing same initial point without any answer. 

Therefore, this makes me to believe that truth is just a illusion of mind to search a never mending answer which is not possible in this going on time.

And also whatever conslucion I draw, always there will reamin in my heart a question as ," WHAT IS TRUTH?"

THANK YOU.
