You cannot possibly understand everything that comes to pass in this beautiful and tragic life.
There is simply too much complexity to it all.
Assuming you know what is happening and why will lead to all sorts of absurd conclusions and decisions.
Of course, you need some level of certainty in your life just to function.
You need to know that there is some truth that is constant and reliable.
But even if you are right about certain things, it does not mean that you understand the how and why of what is happening at the deepest levels of truth.
The truth is far too complex and multidimensional.
The more confident you are in your understanding of the truth, the more of the truth you shut yourself off to because the truth is far greater than your understanding can grasp.
