Another current thread with sam trying to fix yiddishkeit un ken hashkafa. I dont care to bring up all the past examples. Even if someone were to have encyclopedic knowledge of the torah it means nothing without a mesorah and hashkafa rebbi to talmid. Torah tapes are not a rebbi (as should be obvious but nevertheless explicitly stated in the gemara that one needs to see the rebbi teaching).
And lulei dmistafina isn’t just some rhetoric like nisht oif shabbos geredt.
