Sometimes the truth covers a great deal, i.e the truth itself. It covers another truth which is far more persuasive and elusive than the one we see, the truth itself hides the truth, it demonstrates it's ability to torment souls within, to move to the sides of ocean, to go beyond space to reveal it's own true self.
Once a truth is found out another one is deserted, to be thrown in the silent corridors of darkness. Sometimes they are more important like; like the friendship which hides love or a painting hiding the bare walls. Both are true, and in both these situations the friendship and the painting are both a truth, which are hiding the other truth, i.e. the love and bare walls. Though love is the most indispensible part of our lives, still we sometimes need to hide it, till the time is right for it to be known.
