Let us take a close look at truth. Firstly, the word 'truth' comes from an Old English word which meant 'fidelity', having to do with 'exactness'. Truth is the recognition of something 'as it is', or rather as a thing is commonly recognized and accepted as being by use of concrete terms. In a word, suppose someone were to refer to a wall as a door, this would expose the person as being inauthentic to truth.
General statements which lack details often lead people to incorrect conclusions, as well as wrong actions based upon these preconceived notions. Thus, a belief in generalities, such as, 'My religion is the only true religion and all other religions are false' will always lead to conflicts. General statements tend to consist of a low level of truth which causes one to be easily misled. Hence,a generality requires a careful examination for missing details without assumptions as means of discovering the truth.
An exact truth is determined by the person who created it. A liar knows that he is lying because he created the lie to begin with, thus knowing the truth about the lie, and the lie will persist as long as the underlying truth is not exposed. As soon as the truth is exposed a resolution is reached. Thus, if a problem or conflict is persisting, the underlying truth is not known. Because if it were known the problem will no longer persist. This is a fundamental test of truth.
Thus, truth is covered by appearances to the degree generalities are enforced, and awareness is denied. The problem with truth reduces to the problem of attachment to what one already believes in without understanding. However, no person's perception of truth should be condemned just because it is different from yours, because truth is never absolute. Truth is always subject to a viewpoint, and one should bear in mind that finite belief is no substitute for an understanding of the Infinite. Effort of each person should always be to strive for higher levels of truth without making others wrong.
