Rape of Rambha Ravana is regarded to have once caught sight of the apsara Rambha and was filled with lust. Even as the apsara resisted his advances by asserting that she was his daughter-in-law, he raped her. When she reported this to her husband, Nalakuvara, he cursed Ravana to be unable to cause violence to any woman who did not consent to being with him, his head splitting into a number of pieces if he did so. This incident is stated to explain why Ravana could not force the abducted Sita to submit to his desire.
