On Shabbos I came across a parsaha sheet from the previous week, Shabbos Nachamu, about its relationship with Perek Shirah and the bat. Referring to the bat's verse in Perek Shirah, of nachamu nachamu ami, it presented a beautiful explanation of how the bat symbolizes perseverance and triumph through exiles. Just as the bat hangs upside-down, so too the world in exile is a topsy-turvy world. And just as the bat navigates through darkness via sonar, so too we can navigate through the dark night of exile until it lifts to reveal the dawn.
There's no real harm done as a result of the error in the parasha sheet that I saw. It's an inspirational piece of writing. Still, it is alarming to see that an error of judgment that I made at the age of twenty-three is being adopted and elaborated upon fourteen years later!
