J K Rowling, in her Harry Potter series, has given a very interesting concept – that of a Pensieve. For the uninitiated, a pensieve is a stone basin in which witches/wizards can extract and view memories! The Pensieve can also be used to relieve the mind of too many memories, allowing the mind to be free of overburdening and clutter.
I guess if there was a way to check what’s going on in the mind of an average human being, then the noise would be huge enough to cause an acoustic explosion. Can’t say what would happen if the mind of a an above average thinker could be read! It’s rightly said that “Ignorance is Bliss”. Life would be so much simpler without knowing certain things. Or if you cannot escape knowing something – which hurts you like a shrapnel embedded inside you, then it would have been so much easier to have the pensieve wherein you could simply extract it from your mind and unburden yourself. I wish we “muggles” could also find some way!
