That is why we come to earth....

Life on earth is all about duality.  Which is why there are potentials for such extremes of experience.  
The place we come from considers earth a hard place to be and yet the place where we can learn the most.  It's difficult to overcome some of the obstacles that are placed, that we place, in our paths.   We make the choice to come here knowing how difficult it can be.   The earth, the duality, living here, making choices, attempting to overcome obstacles and we still come.  Over and over again. 
“You are here to enable the divine purpose of the Universe to unfold. That is how important you are!”
― Eckhart Tolle
That is why we come to earth... over and over again....
