This is a tricky one for me. Because it requires that you not look for a source of blame for every obstacle that arises or every thing that goes ‘wrong’ in your life. You instead let things go and you look closely at the situation to uncover oany ways that you may have acted unskillfully and helped cause it to be difficult. But this does not mean that you fall into habitual, meaningless self-blame for everything nor that you should not blow the whistle on those who are shirking their duties or who are corrupt.
The slogan implies that you accept blame for a given situation when you notice the urge to blame someone else as a way to push past blame and judgment into a search for mutually acceptable answers.
