On the way Jatâyu, the son of Aruna, met Râvana; and a terrible fight then ensued between the two, when the evil minded Râvana, the king of the Demons, killed Jatâyu. Râvana carried Sîtâ to Lankâ. Then Sîtâ cried like a forlorn deer and Râvana kept her in the As’oka forest (Jaffna),
surrounded and guarded by the Râksasis. The king of Lankâ tempted Sîtâ with comforting words, and the kingdoms, etc., but she never swerved from her own pure and stainless chastity.
