There's a DS9 episode featuring a klingon lawyer (I forget which episode it is). THe lawyer has a few pieces of dialogue where they view the legal process as a battle just like any other klingon views a fight. Since then it's been my head canon that plenty of klingons are around doing plenty of stuff other than fighting but view it in terms of hunting, battle (with something) and honour. I wish more of this were touched on in Trek.
Like ... klingon monks and religion ... what's the culture of pursuing that for a klingon?
