Aranya Kanda, the Book of the Forest, follows Rama, Sita and Lakshmana through years of exile among sages and demons in the Dandaka forest, encountering the demoness Shurpanakha, sister of the demon king Ravana, who proposes marriage to Rama, is mocked and rejected, then attacks Sita in jealous fury and is disfigured in return, her nose and ears cut off by Lakshmana, an injury that sends her fleeing to her brother Ravana with a vivid, provoking account of Sita's beauty.
Ravana, resolving to abduct Sita, sends the shape-shifting demon Maricha disguised as an extraordinarily beautiful golden deer to lure Rama away from their forest dwelling in pursuit; Rama, unable to resist Sita's pleading, gives chase and kills the deer, which cries out in Rama's own voice as it dies, prompting Sita to send an anxious Lakshmana after him despite his own reluctance to leave her unguarded. With both brothers away, Ravana approaches Sita disguised as a wandering ascetic, then reveals himself and abducts her by force, carrying her off by aerial chariot as the vulture king Jatayu, a longtime friend of Dasharatha's family, attempts to stop him and is mortally wounded in the struggle, living only long enough to tell the returning Rama what happened before dying.
