Aranya Kanda (The Book of the forest) is the third book of the Valmiki Ramayana, which is one of the two great epic poems of India, the other being the Mahabharata. The book consists of 75 sargas (sometimes translated as chapters or cantos) of Sanskrit verse. This describes journey of Rama, Sita and Lakshmana in the forest.
Rama, Sita and Lakshmana journeyed southward along the banks of river Godavari, where they built cottages and lived off the land. At the Panchavati forest they are visited by a rakshasa woman, Surpanakha, the sister of Ravana. She attempts to seduce the brothers and, failing in this, attempts to kill Sita. Lakshmana stops her by cutting off her nose and ears. Hearing of this, her demon brother, Khara, organises an attack against the princes. Rama annihilates Khara and his demons.
When news of these events reaches Ravana, he resolves to destroy Rama by capturing Sita with the aid of the rakshasa Maricha. Maricha, assuming the form of a golden deer, captivates Sita’s attention. Entranced by the beauty of the deer, Sita pleads with Rama to capture it. Lord Rama, aware that this is the play of the demons, is unable to dissuade Sita from her desire and chases the deer into the forest, leaving Sita under Lakshmana’s guard. After some time Sita hears Rama calling out to her; afraid for his life she insists that Lakshmana rush to his aid. Lakshmana tries to assure her that Rama is invincible, and that it is best if he continues to follow Rama’s orders to protect her. On the verge of hysterics Sita insists that it is not she but Rama who needs Lakshmana’s help. He obeys her wish but stipulates that she is not to leave the cottage or entertain any strangers. He draws a chalk outline, the Lakshmana rekha around the cottage and casts a spell on it that prevents anyone from entering the boundary but allows people to exit. Finally with the coast clear, Ravana appears in the guise of an ascetic requesting Sita’s hospitality. Unaware of the devious plan of her guest, Sita is tricked into leaving the rekha and then forcibly carried away by the evil Ravana.
Jatayu, a vulture,tries to rescue Sita, but is mortally wounded. At Lanka Sita is kept under the heavy guard of rakshasis. Ravana demands Sita marry him, but Sita, eternally devoted to Rama, refuses. Rama and Lakshmana learn about Sita’s abduction from Jadayu, and immediately set out to save her. During their search, they meet the demon Kabandha and the ascetic Shabari, who direct them towards Sugriva and Hanuman.
