Sechel….
Please read my post. Rav Shach holds like the Taz. Nobody said kabalah isn’t Torah. The question is if you’re mekayam talmud Torah with it, because talmud Torah is to learn tanach and gemara to come to halachos. The shulchan aruch harav even, can hold that kabalah isn’t talmud Torah, if you go through his psakim.
He doesn’t write that it isn’t Torah or that it is; that wasn’t his discussion. His discussion is if you’re mekayam talmud Torah with it or not.
In maaseh ish talmidim testify that the chazon ish was an expert in kabalah too.
