The Week lists Trancendence-Perfection by Sri Chinmoy as one of the 10 works of literature that were exceptionally hard to write
Before his death in 2007, Indian spiritual master Sri Chinmoy wrote at least 1,000 books, 20,000 songs, and 115,000 poems. Some he penned in his mother tongue, Bengali, and some in his second language, English. His poems won numerous awards and inspired countless writers and musicians.
And while Sri Chinmoy was clearly a fast writer, he was never as quick as on November 1, 1975, when he wrote Transcendence-Perfection, a collection of 843 poems — all written in 24 hours.
