Relationships
It is wise to reflect on the saying "Treat others as you would expect to be treated yourself". I know it is not always possible to turn the other cheek, living on Earth. But at the very least make the effort.
Try where you can, to be even-handed with others. You never know who they are on the other level. Maybe it was their task to be an obstacle in your way in life, in order to grow your spirit. Maybe they are making a great sacrifice to their own spirit in order to grow yours.
Maybe not!
The point is, we do know what we are here for. That should be our focus and we know that that does not involve hurting any of our fellow travelers.
