Ramacharitamanas (रामचरितमानस, 1574–1576), "The Mānasa lake brimming over with the exploits of Lord Rāma" is an Awadhi rendering of the Ramayana narrative. It is the longest and earliest work of Tulsidas, and draws from various sources including the Ramayana of Valmiki, the Adhyatma Ramayana, the Prasannaraghava and Hanuman Nataka. The work consists of around 12,800 lines divided into 1073 stanzas, which are groups of Chaupais separated by Dohas or Sorthas. It is divided into seven books (Kands) like the Ramayana of Valmiki, and is around one-third of the size of Valmiki's Ramayana. The work is composed in 18 metres which include ten Sanskrit metres (Anushtup, Shardulvikridit, Vasantatilaka, Vamshashta, Upajati, Pramanika, Malini, Sragdhara, Rathoddhata and Bhujangaprayata) and eight Prakrit metres (Soratha, Doha, Chaupai, Harigitika, Tribhangi, Chaupaiya, Trotaka and Tomara). It is popularly referred to as Tulsikrit Ramayana, literally The Ramayana composed by Tulsidas. The work has been acclaimed as "the living sum of Indian culture", "the tallest tree in the magic garden of medieval Indian poesy", "the greatest book of all devotional literature", "the Bible of Northern India", and "the best and most trustworthy guide to the popular living faith of its people."
