The idea that every concept can be translated is probably a false one. Ideas are built on cultures, cultures are described by language you can't change one without changing another. So when describing an idea generated by a culture, using a secondary idea and secondary culture, you will lose things.
That is why (for example) nirvana, has a bunch of translations: awakening, calmness, relief, void/voidless, the light, nothingness, or (my favourite) phew. Because we don't have the context to properly describe that in the west (latin-germanic based languages), so we need a bunch of other concepts that kind of point at it.
I'm saying language and culture are inextricably linked. And not 100% compatible with all other languages and cultures.
The Buddhist Mahayana concept of "emptiness" requires at the very least a few paragraphs to have a grasp, at best a couple of books on your belt. Same with "concentration" (samadhi), "insight" (vipassana), "life-energy" (prana), and so on and so forth.
To the uninformed reader they certainly add that confusion, but for someone versed in Eastern philosophy it's essential that the original concepts be preserved.
Seems like mild euro-centrism.
If koti means corner, there is no reason that 'koti' should appear in a translation instead of corner otherwise you are giving it a special importance that distracts from the text's true meaning. Almost every translation of indian philosophy suffers from this fetish for the sanskrit language and as beautiful as sanskrit is, it shouldn't contaminate the purpose of a translation.
