Karma is rather like the placement of dominos in lines on end and the cause and effect interaction that results. Some dominos you may place, or affect, to some extent, the direction in which they fall. Most domino's placement and fall are beyond your ability to affect.
Therefore, act impeccably.
"When you have eaten, wash your bowl".
And when, inevitably, the dominos fall in a way you perceive to be negative, remember that one thing you can always affect is your response to events. That is, YOU CHOOSE how you think, feel, and behave in response to stimuli.
Do not expect divine intervention (positive or negative). Rather, perceive the on-going divine interaction.
