متن اصلی - لاتین - Sum Illud Fac

Why the words are in caps? I don't see the reason of it. And I would put comma or full stop after "sum"...

In caps according to what Aneta says.

Bridge, maybe for you, Lilly.
"I am (here). (Just) Do it"

There isn't full stop in the Latin source, but it is needed in English.
