If you have been learning the Hanuman Chalisa you will want to read Sri Ramchritmanas_Roman ( PDF).
It is considered to be the Bible of North India and was written by the same author as the Hanuman Chalisa, Tulsidas. While it is based on the Sage Valmiki’s Ramayana (which was written 1000 years prior) it gives an insightful view of the beliefs and trends prevalent in Medieval North India. These concepts are delivered through the mouths of such heroes as Lord Shiva, Lord Ram and Lord Hanuman, and are skilfully woven into the stories of Ram. The text has a comical slant at times and written in the same meter as the Hanuman Chalisa (chaupai) adds to its up beat effect.
