Different realms,Different beings,Different times - How do they understand what we are saying?

I have seen how some Sutras / Suttas start with an open invitation to many beings to come and hear the words of the Lord. Now this makes sense as it was a teaching given by Lord Buddha to his followers.But now the times have changed "Pali" as a language is dead. It gave birth to many new languages and died in the process. So today we say the same suttas and some keep it original and some use their own translation. ---- - So how does the translation happen? Is there any mentioning on how beings in different realms understand a single language, I mean even we don't use "Pali" now so how does it happen? --- - And there is another side to this too. There are some really bad realms, like "Pretha" beings. They have only suffering with the exception of few having some comforts like clothes and food.These beings have no way of learning, So how does it happen, how do they understand the teaching when they come to hear it? ---- If you can,provide any Sutta / Sutra referance
