Truth is an abstract term which refers to facts. Facts depend upon a stability in what is real. This stability must be observed for it to be a fact. But observations depend upon perception. What I observe as true through perception another person may also observe as true and thus it becomes a proven fact when everybody can observe it, at will. But, if that which we are observing changes form (and all things eventually do) then it is not a fact. Our mind has simply made it real and true for us at this moment. It is not stable and it is only real temporarily and therefore is meaningless. Everything is constantly changing and in a constant motion. What is real today, will not be real tomorrow. What is true at this moment about our Universe will not be true trillions of years into the future.The only true reality is that nothing is stable or eternally true, therefore there is no such thing as truth or fact or reality. Our entire existence is meaningless. All arguments and discussions are based off of the concept of meaning and purpose. There is no purpose or meaning that we know of and if we discover a meaning or a purpose it will not hold eternally true, therefore it is nothing more than a delusion. Existence is a Universal Delusion. We are all part of a totality that takes on many forms in some sort of eternal dance which has no purpose or meaning to it whatsoever. The dance will go on and we will play our part over and over again. The matter which is our body will take on different forms and the energy which is within us will as well. Nothing we accomplish matters. Our failures and successes mean absolutely nothing. Everything we fight and die for is worthless and nothing . . . absolutely nothing will remain in tact. The Universal Delusion is that we have control over anything. We control nothing. The key to true freedom is simply to let go.
