Srimati Kunti devi is one of the main characters of Mahabharata who is famous for her surrender to the supreme lord Sri Krishna, who is by all means accessible to his devotees under all circumstances.
Kunti Maharani was the daughter of Shurasena and foster daughter of King Kuntibhoja. He is the sister of Vasudev, the father of Sri Krishna, therefore, she is the aunt of Lord Krishna.
Although she is elder in her age, still she offers her prayers to the supreme lord since she understands that Krishna is the supreme personality of godhead.
While she was in the house of her foster father Kuntibhoja, she selflessly served the Rishi Durvasa and he, in return, being pleased by her service, gave him a mantra using which she could call any demigod and he will reward him a gift.
Out of her own curiosity, she called Suryadev and when he arrived, he asked her to ask for a boon to which she told the reality. But suryadev replied that he is duty bound to give him a reward and gave him Karna, his son.
Afraid of the world, she put Karna in a basket and rendered afloat in the river. She was married to king Pandu and then, by the fate King Pandu was cursed by Rishi Kindama to die as soon as he would try to indulge in sensual gratification.
Eventually, King Pandu asked Kunti to beget sons and she begot 3 sons, Yudhishthira, Bheema and Arjuna. When further persuaded, she asked him to stop and wait for one year.
Due to her misfortune, his husband died when he tried to embrace his another wife, Madri and she was left alone alongwith 5 Pandavas.
When the Pandavas returned to Hastinapur, there was a succession crisis. Duryodhana claimed to be the next heir for the kingdom. Dhritarashtra named Yudhishthira as his heir, enraging Duryodhana. With the help of Shakuni, Duryodhana planned to burn the Pandavas and Kunti in a Lakshagraha while they were on a festival at Varnavat. But with early warning and aid from Vidura, the Pandavas and Kunti fake their death and escape the burning house. They travel the countryside, disguised as brahmins.
The prayers offered by her to Lord Krishna represent the feeling of surrender of a devotee. She prays to Lord Hari as (Srimad Bhagwatam 1.8.18-20)
īśvaraṁ prakṛteḥ param
antar bahir avasthitam
na lakṣyase mūḍha-dṛśā
naṭo nāṭyadharo yathā
kathaṁ paśyema hi striyaḥ
