The original Sundara Kanda is in Sanskrit and was composed by Valmiki, who was the primary to scripturally record the Ramayana. Sundara Kanda is that the only chapter of the Ramayana during which the hero isn't Rama, but rather Hanuman. Anjani mata was calling Hanuman Sundara so Rishi Valmiki picked this name over others as this kanda deals mainly with Hanuman’s journey to Lanka. Other versions of the Sundara Kanda exist in other languages also , as an example in Awadhi, the language during which the saint Tulsidas wrote the Ramacharitamanas.
