I believe the answer is:
karma
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">good or bad luck</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for karma that I've seen before include "Buddhist principle of inevitable consequence" , "moral reckoning" , "Retribution" , "reaping what's sown" , "Lifetime's actions that set fate for next life" .)
