Tulsidas wrote 12 books, but, by far, the most important is the Ramacharitamanas (the holy Lakes of the Acts of Ram), a Ramayana written in old Hindi (Avadhi) couplets. The book was written under the direction of Hanuman himself. It is read all over North India, and particularly during the time of the Ramlila. It is sung aloud in large groups for devotional purposes.
