Interesting Sōtō history tidbit

 I'm not one on being too sectarian,  and I don't like bashing other schools at all, but this piece from Dosho Port explains a lot about not only why Sōtō folks often seem obsessed with Dōgen, but also how the Sanbo Kyodan lineage came about.  It too, in my view, doesn't really bash Sōtō, but historically it's fascinating.
