Yabia – our concern for halacha…even the smallest kutzo shel yud, is unwavering and not dependent on anything else going on around us. “Alll Hashem has in this world is 4 amos of halacha”, it is everything to us
When the baalei tosfos were about to be murdered by crusaders, their last energy they spent writing a regular tosfos on bava basra. They wrote it in their holy blood. They were martyred the following day.
They didn’t write ethical exhortations or liturgical poems – the “big things” that a commoner would think of… they wrote nothing but halacha, and a halacha that isn’t practically applicable nonetheless.
All we have is Hashem, and all He has is Torah.
