“is not meant to be taken by us commoners literally” courtesy of TamMHO. Of course this doesn’t stop many who should know better from publsihing snippets of Zohar wherever they please, including in the siddur.
Case in point: I shop for shabbos in the shuk mahane Yehuda, where a collector for a Kabbalist Yeshiva collects on frequent rounds that coincide with my shopping. I figure they learn standard Torah there, so I give a five, ten or twenty shekel donation. He obviously gets generally less, because he is more than happy to see me. He always offers a receipt, which I refuse, saying receipts are from shamayim. I also refuse the leaflets he always offers for shabbos reading, claiming I have enough to read, and I hurry away. Once he caught me sitting down at a local Mincha, and I accepted the leaflet. I found in it a small piece, a quote from Zohar, on a pasuk in Emor that applied a clear reference to Hashem to a certain person. To me, the commoner, this seems like outright kefira if nothing worse. I need a shayla chochom about continuing to give this mosad tzedaka.
