PewDiePie mentioned Japanese Death Poems by Yoel Hoffmann 1 times

The next book I want to talk about is Japanese Death Poems Written by Zen Monks and Haiku Poets on the Verge of Death [...] So the book starts off with zen buddhism which is actually my favourite part of the book. I didn't think I would enjoy it. I kind of wanted to just jump to the haikus but it just features incredible stories of zen buddhists or masters that died sitting upright and right after they finished their last brush strokes of their poem. I don't know if that is true or not, but it just sounds badass! [...] It's a great book. It features a lot of haikus that's never been translated before so I really, really loved it.
