The world is a mirror reflection of your dominant thought. Even if you are in the best of your moods and something spoils it, it’s that hidden inner dominant feeling which was camouflaged by the outer happy mood. The universe is trying to remind you that you have unresolved issues that you need to take care off within yourself.
Life is so simple, if we see it with a non-judgmental perspective. If anyone says something to you and you feel offended, its your unresolved ego issue or insecurity that is making you feel bad. You should be thanking the other person (mentally of course, or else you will be tagged as crazy) to help you identify that feeling in you.
