I think I spotted a typo in the pdf of book 5

Page 54, side bar in the bottom right corner there is apparently a missing "may," at least I'm guessing from the context.

The sentence reads: "The Disciple’s master be the same person as her guru, since that’s more about the big-picture stuff than anything else, but that’s not required."


Paging @Justin_Alexander, who keeps track of errata for future printings.

Nice catch, PK!
