uh . . . karmathartic?
how'd you come up with that?
Long story, short: dad jokes. Wordplay. For real.
As a Dad, it's my job to keep everyone in a fresh supply of puns, spoonerisms, and portmanteaus. When my daughter starts wheezing during one of her frequent laughing fits, we call that a laughsma attack. One of the main characters in her bedtime stories is a globe-trotting chicken named Sailor Twift (see Taylor Swift).
For better or worse, my head's just hardwired this way. And Karmathartic is a portmanteau combining the words karma, which in Eastern philosophy, according to its most rudimentary definition, simply means cause and effect, or action, and catharsis, which, in Western psychology, denotes self-discovery through creative expression, particularly writing, but through all art forms.
So, Karmathartic means - perhaps - deliberately cultivating, through creative expression, the causes and conditions for transformation and understanding. Something like that.
