> try to translate a piece of classic buddhist text to Latvian

Here is a translation of a classic buddhist sūtra in Latvian: http://www.ugis.info/?t#sutra_

> You will simply have no words to express what you need

That is a challenge that all translators face, no matter the language pair. There are no direct equivalents of "अभिधर्म" or "Ānanda" in any of the Western languages either, be it Latvian, English or Welsh. Incidentally, both Lithuanian and Latvian happen to be closer to Sanskrit than the latter. Again, I don't quite see the point you're making. Care to elaborate?
