The Four Valleys (Persian: چهار وادی Chahár Vádí) is a book written in Persian by Baháʼu'lláh, the founder of the Baháʼí Faith. The Seven Valleys (Persian: هفت وادی Haft-Vádí) was also written by Baháʼu'lláh, and the two books are usually published together under the title The Seven Valleys and the Four Valleys. The two books are distinctly different and have no direct relation. In February 2019 an authorized translation of both titles was published by the Baháʼí World Centre in the collection The Call of the Divine Beloved. Source: Wikipedia (en)
