If you're into poetry, especially if you into German poetry (Rilke, was a Czech though), this book of collected poems is a must read. You can quite literally see Rilke grow and become one of the greatest poets of his time... Maybe even of the 20th century. You read one poem and think: this can't get any better. And then, on the next page there's one that leaves you even more breathless. See it, buy it, read it.
