The theme of Adar is "Ad Deloh Yoda Ben Arur Haman Leboruch Mordechai", spiritualy that is accomplished, where a person acknowledges, that everything that happens in this world and to every person, whether it appears to be good or bad, is beyond our understanding and from G-D.

That is why we bow during Modim, to acknowledge every day, that everything that happens is beyond our understanding.
