What the Truth is 1

Can any one define exactly what the truth is?
Is it what other tells us making us to believe it or what we fell it is correct or right to believe it?
We actually does not know what the truth actually is as most of the time we keep blind faith on what other tells us or on the situation it is either created or in front of our eyes. The truth about anything is known better only by the person who tell us but many a times he does not want to narrate it due to many reason in his mind or base on the situation at that particular time. In most of the cases truth cannot be come forward as it is or exactly as one expect. Why such thing happen in the society as whole or why people act in that fashion is the big unsolved question many time. But what to do one has to accept the fact as it comes forward. This is life and one has to move with it.
