From a letter

You complain that peace in the home is, for you, wrought with obstacles.

All of us today are souls that have been here before. In general, we return on unfinished business. Certainly, we are all responsible for doing all the good we can, and avoiding everything harmful. But that certain unfinished business, that is where the most obstacles shall be.

And those obstacles will be your only clue as to what business you are here to finish.
