Nirvana and revenge are two very different concepts and therefore, finding synonyms for "nirvana revenge" can be a little challenging. However, some possible options could be "blissful vindication," "ultimate retribution," "serene retaliation," or "tranquil payback." These phrases evoke a sense of peacefulness or satisfaction that comes with accomplishing a goal or seeking justice. It is important to note that revenge typically involves harmful or negative actions towards another person, whereas nirvana is a state of ultimate peace and happiness. So while these phrases may have a similar meaning, they should not be used interchangeably.
