Hanuman meeting Sita in Ashokvana is the central and most famous event of Sundara Kanda (the Book of Beauty). This Kanda describes Hanuman's journey to Lanka, his search for Sita, and their emotional meeting in the Ashoka grove where Ravana had imprisoned her. Sundara Kanda is named 'beautiful' because Hanuman's selfless devotion and heroic actions exemplify beauty of character.
