A little mystery is a good thing. It ties into acceptance, into letting go, into believing in something beyond your own normal perspective and beyond rationality. Into opening your mind to possibilities. All survival skills for everyday life.
So, how do I do cultivate a little mystery in my life? I like to read about weird things. I read about the Loch Ness Monster or miracles. I read about ghosts or angels. Prophecies or tall-tales. Whatever the subject you read about, don't try to rationalize or discount it. Just pretend for one moment it is possible; just end the piece with two simple but powerful words: "Maybe so."
Adopting that stance toward life can lead to happier mental climates. Doesn't matter if the mystery is true or logical or not; that is not the point of "maybe so". "Maybe so" isn't about truth; rather, it is a key to opening up a world of possibilities you never bothered to see before. Such a mindset sees possibilities instead of impossibilities. Such a mindset allows happiness in.
Try on a little mystery today, and let me know how it goes for you.
