on the sidebar it read “their teaching” as in of the lineage, but I would think more grammatically correct would be its teachings, the teachings of the lineage. The lineage being an “it”, a thing. A tradition too would be an it.
Not a big deal or nothing, but being a bit pedantic, felt I could try to suggest it.
(I thought of sending this through modmail, butI haven’t found modmail yet in lemmy? Is it just absent?)
Might be a British English vs. American English thing: https://en.wikipedia.org/wiki/American_and_British_English_grammatical_differences#Subject–verb_agreement
