Morning, and welcome to the Forums! My name's ngabwI', and I handle (unofficially) alot of the requests for translations around here. There's also another member of the Forums, Qunchuy, who is more skillful than myself.
I seem to remember a request something like this, either here or on the KLI's list from many moons ago.
Your first translation request,
The way of my life, creates the way of my death
will depend on how you want to translate "way". My suggestion is {mIw} "process for doing something". So your sentence would be:
{HeghwIj mIw chenmoH yInwIj mIw}
"My life's process creates my death's process"
Now, onto your second request.
Life is Pain, Death is Pain
Oddly enough, this one is much simpler, with fewer choices to make.
Encoding directly to Klingon, we arrive at:
{'oy' 'oH yIn'e', 'oy' 'oH Hegh'e'}
"Life is Pain, Death is Pain"
Another, not so "noun-based" option, is to say
"Life hurts, Death hurts"
{'oy'moH yIn, 'oy'moH Hegh}
The above "feels" "more {tlhIngan}, but this is your choice. I fully support any informed decisions.
If the first sentence isn't quite what you're after, post again, and we'll work on it together. }}: )
