The original Sundara Kanda is in Sanskrit, and was composed in popular tradition by Valmiki, who was the first to scripturally record the Ramayana.

Sundara Kanda is the only chapter of the Ramayana in which the principal protagonist is not Rama, but Hanuman. The work depicts the adventures of Hanuman and his selflessness, strength, and devotion to Rama are emphasised in the text. Hanuman is believed to have been fondly called “Sundara” by his mother Anjana, and Sage Valmiki is stated to have chosen this name over others as the Sundara Kanda is about Hanuman’s journey to Lanka
