” it is very easy to misunderstand the exact meaning. In fact, it is almost impossible not to, since there is no such thing as a precise translation.”
“That makes no sense. If that was even remotely true there would be no English translations. They would all be nichshol everyone who reads them. Did the gedolim miss that point when endorsing these volumes? Or was the point to say people who study from the English versions are inferior because they are not REALLY understanding Torah.”
Translations are b’dieved and a horaas sha’ah. If you read the haskamos to halacha sefarim, they are generally written with a lot of reservations. Many halacha sefarim start off by warning the readers not to posken from them, and to look up the sources in the original.
There is nothing wrong with reading a translation or a concise halacha sefer if you understand what its purpose is and is not. I am not familiar with the Sefer you quoted, but it sounds to me as though it is just meant to make people aware of the general halachos.
The people who write these sefarim understand that not everyone will be able to learn the halachos in depth for whatever reason (and there can be many reasons for that), so they want to make sure that people are at least aware of the general principles, so that most of the time they won’t be “nechshol” and so that they will know when to ask.
Again, if you think that there is a problem here, I think it’s a good idea for you to ask a sheilah about it. There are many reasons why I think that is not the case – I mentioned some. However, many of them are things that it is not possible for me to discuss in this forum.
But please keep in mind, as you yourself have mentioned in the past – there are all kinds of Rabbanim in the world, so make sure that you ask the right one. When it comes to Hilchos Loshon Hara, you really need to make sure that you ask someone who is a baki in this particular area and has lots of experience asking sheilahs of this sort.
It is not merely a matter of being a Talmid Chacham and knowing the halachos thoroughly – it also takes a lot of perception and understanding of people. And again, I think that the CCHF can direct you in this matter. (and no, I don’t work for them).
