Sechel, please show me one source in the Gaon, tzlach, rav shlomo eiger, or any of the other strong opponents of chasidus, where they say that “this person came and told us to do teshuva”
Or, cite a source from a chasidishe sefer written at the time, like the toldos, kedushas levi, tanya, etc… Which says that the gedolei yisroel need to do teshuva and that they think they’re perfect the way they are.
I’m not interested in letters or sichos or whatever from contemporary people. Show me one source in the talmidei habesh”t or the misnagdim which says anything like what you’re accusing them of saying.
You’re not familiar with the gadol who saved an entire country from reform, and im the one who needs to learn history?
Seriously?
