Find that which doesn't change

I will tell you what to look for. Find that that doesn't change. It is unchanging and that which is undeniable and therefore verifiable. So the truth cannot be that which changes because if you say the truth is red and tomorrow it is yellow then this truth is of no value there must be a truth which is unchanging and a truth if it is just conceptual but not our living experience then all concepts can be denied. Even I am awareness if it is only a concept can be denied. Who is somebody can come and argue with you and say there is no awareness. It is completely deniable if it is just conceptual. So what is the truth? What is undeniable and unchanging? And using this question all of our mental knowledge will start to disintegrate.
