who did not sleep for 14 years in ramayana
Urmila As the night fell on the first day of the exile, Lakshmana stood guard over Ram and Sita with a strong resolve not to sleep until the exile ended. As Lakshmana stood guard over his brother's dwelling, a resplendent goddess called Nidra Devi manifested before Lakshmana. On Lakshmana's enquiry, she introduced herself as the Goddess of Sleep and informed him that not sleeping for fourteen years is an act of defiance against nature. Lakshmana requested Nidra Devi for a way out so that he could carry out his Dharma towards his brother. Impressed by Lakshmana's devotion towards his brother, Nidra Devi put forth a workaround that if someone bears the burden of Lakshmana's share of sleep for fourteen years, he could have the exemption for fourteen years. Lakshmana requested Nidra Devi to approach his wife, Urmila, to help him.
Sita Sita, in her youth, marries Lord Rama, the prince of Ayodhya. After marriage, she goes to exile with her husband and brother-in-law Lakshmana. While in exile, the trio settle in the Dandaka forest from where she is abducted by Ravana, the Rakshasa king of Lanka. She is imprisoned in Ashoka Vatika in Lanka until she is rescued by Rama, who slays her captor. After the war, Rama asks Sita to undergo Agni Pariksha (an ordeal of fire) by which she proves her purity before she is accepted by Rama, which for the first time made his brother Lakshmana get angry at him.
