Truth will set you free!!

The truth will set you free - reads a message boldly scrawled across a book my colleague is carrying; and thus I wonder! Does the truth really set you free, and if it does then does this freedom always lead to happiness? I believe that the ultimate aim in life is happiness (param sukh - and I don't mean Shinde's version of it); so does the truth give that to you? Isn't it true that at times what we believe as true is much more beautiful than the truth itself? That the ultimate discovery of the truth often results in the bursting of a bubble of joy/hope that existed? Is it better to not know that someone has cheated you in the past when it really doesn't affect you any longer? Wouldn't you be better off believing that all your friends, with whom you no longer are in touch, are doing well rather than knowing the truth that one of them is suffering or worse? So maybe the truth does set you free but I don't know if I want that freedom at times. At others I just am content with a distorted truth that makes me feel good. But then is it the truth at all, if it is distorted? What is actually the truth then? The chandelier or the light that it emits?
