The Hanuman Chalisa is much more than just a collection of forty -odd verses. Events from the Itihasa and Purana have been wrapped around a core of philosophy to create these magical lines. Along with a verse-by-verse meaning in simple English, this book tries to establish a pattern in the arrangement of the text. It takes into account the viewpoints of both the Valmiki Ramayan and the Ramcharitmanas and tries to analyse the verses of the Chalisa in the background of the Vedas, Puranas, different versions of the Ramayana and other books authored by Tulasi Das. Very few commentaries or even expanded translations exist on the Hanuman Chalisa. This book is a small effort to fill the gap.
