They protect you in many mysterious ways.
Strange things can happen in your life that have no practical explanation.
They just feel mystical for some reason.
They effect where you go or what you were going to do.
Angels have been known to make physical and nonphysical changes in your circumstances that effect what you do- where you go.
So if the unexplained event changes the course of your physical life a little it might have been an angel interceding.
It is truly a blessing.
You may never know why.
