Kaikeya state is said to be located between the current Caucasus, Kashmir, Afghanistan, and Punjab. According to mythology, King Ashwapati had one brother, Vrihadshrav, and his daughter was Princess Rekha. Rekha has been compared to Vishalakshi, a big-eyed Hindu goddess and extremely clever. Princess Rekha had taken something unsuitable to keep her form at all times, causing her body to bend and become unattractive. She was a victim of Tridosha owing to the use of syrup, and her body was tilted in three places, according to one of the reasons for her being ugly. Due to this condition. As a result, her name was changed to Manthara.

After a few time, finally, the day came when Maharaja Dasaratha announced his eldest son Rama's coronation in the Chaitra month, Kubri Manthara came and informed Kaikeyi. Kaikeyi was overjoyed when she learned of this and gifted Manthara with a gem in exchange. Manthara threw the jewel and gave Kaikeyi a thorough explanation. But Kaikeyi ignored Manthara and claimed that it is Raghukul's custom for only the eldest son to inherit the throne, and Ram is adored by all.

Then, disguised as Manthara, Kaikeyi remembered his two boons and became suspicious. Actually, King Dasaratha took part in the Devasur Sangram at Indra's request. In this conflict, he was supported by his wife Kaikeyi. During the conflict, Dasaratha was unconscious. Dasharatha was pleased and offered two boons after Kaikeyi got him out of the battlefield while the king was unconscious.

Then Kaikeyi stated that when the time comes, she would ask for the boons. Later, after Manthara filled Kaikeyi's ear, she proceeded to the Kop Bhavan at Manthara's request to remind King Dasaratha of his two boons. Ask for a boon, King Dasaratha replied. Kaikeyi then sought Rama's exile and Bharata's kingdom as a boon. King Dasharatha collapsed to the ground upon hearing Varadasa's words. When Shatrughan learned that Ram had been exiled due to Manthara, he was so furious and kicked Kubri Maasi Manthara's hump.
