'Truth', most of the times, is hidden and unknown to naked eyes. As Mark Twain said, 'Truth is more of a stranger than fiction'. It is like a statue hidden in a raw stone; you carve out unwanted portions, the statue will appear.
'Truth' is, a mystery, a riddle, where countless false-es are covering it. A single false cannot hide a truth; it needs countless of them to hide it! Too many lies lead to a truth! As JK finely says, 'Truth is pathless land'. So only numerous lies cover it and make it hidden!
'Fact' is not 'Truth', always. 'Fact' is what we percieve and 'Truth' is what is real.
