Chalisa is essentially a forty lined composition. Hanuman Chalisa is a set of 40 lined verses composed by Tulsidas in Awadhi. In the last stanza of the Chalisa, it is mentioned that whosoever recited it with full faith in the power of the Lord, will experience the divine grace of Lord Hanuman. Great men have born testimony to the fact that simple recitation of Hanuman Chalisa with unflinching faith in Lord Hanuman can bring the impossible to possibility. Swami Karpatri and Rambhadracharya also believed in the immense power of the Chalisa.http://www.shrihanumanchalisayantra.in/
