<P> In the Ramayana, Trijata appears as a wise old rakshasi, who dreams of Ravana's destruction and Rama's victory . She accompanies Sita on a survey of the battlefield of the war between Rama and Ravana, and reassures Sita of Rama's well - being when Sita sees her husband unconscious and presumes him dead . In later Ramayana adaptations, Trijata becomes the daughter of Vibhishana, the brother of Ravana who sides with Rama . She plays a much greater role in later versions, especially Southeast Asian ones . </P> <P> Barring a few exceptions where Trijata is cast as Ravana's agent, she is generally portrayed as a friend and loyal companion of Sita in her adversity . On numerous occasions, she offers solace to Sita and brings news from the outside world; she also dissuades Sita from committing suicide . After Rama's victory and Ravana's death, Trijata is richly rewarded by Sita and Rama . While some Ramayana adaptations mention her being a devotee of Rama, Southeast Asian versions often depict her as the wife of Rama's monkey general Hanuman, whom she bears a son . She is worshipped as a local goddess in Varanasi and Ujjain; both in India . </P> <P> While Indian, Javanese and Balinese versions of the Ramayana call her Trijata, she is known as Punukay in the Laotian Phra Lak Phra Lam, Benyakai (เบ ญ กาย) in the Thai Ramakien and Devi Seri Jali in the Malay Hikayat Seri Rama . </P> <P> In the original Ramayana by Valmiki, Trijata is described as an aged rakshasi (demoness) who is prominently featured in two incidents . The first takes place in the Sundara Kanda, the epic's fifth book . The kidnapped princess Sita is imprisoned in the Ashoka Vatika of Lanka . The demon - king of Lanka, Ravana has ordered the raskshasis who guard Sita to convince her to marry him by any means possible, since Sita adamantly refuses and is still faithful to her husband Rama . After Ravana leaves, the rakshasis start to harass Sita to compel her to change her will . The aged Trijata intervenes and narrates a prophetic dream that predicts Ravana's doom and Rama's victory . </P>
