Because we all believe in cause and effect, we are convinced that everything that happens has a purpose. Maybe it does have a purpose. However, sometimes things happen so far in advance of the event that they influence that we cannot see the cause and effect. Think a butterfly flapping its wings in Brazil and a storm in England.
We do not have a broad enough vision to see everything and to understand everything. Accepting that we cannot know everything allows us to be at peace with seemingly random events.
We can say good-bye to analyzing life to pieces and say hello to accepting the beauty and the abundance and all the things that are sent our way.
