"Saint Mira is another example. She was a queen who lived in a palace. She was detached from the world, absorbed in God's love, and she did not care for any worldly thing. All the time, she was singing songs for Krishna. Her mother-in-law and sister-in-law did not like this gave her a lot of trouble. But she was so absorbed in love for Krishna that she did not know that her in-laws were plotting against her. One day, Mira's mother-in-law gave her poison, and Mira drank it in the name of Krishna. Nothing happened to her.
Every morning, a gardener would bring Mira a basket filled with flowers for her to offer to Krishna. Her mother-in-law and sister-in-law arranged for a cobra to be put in the basket along with the flowers. The gardener brought the basket and set it before Mira, who happily accepted it. When she opened the basket, there were only flowers, no cobra.
"She would leave her palace and go out onto the road and sing for Krishna. The mother-in-law and sister-in-law did not like her behavior. They did not know why she was acting as she did. Once, Mira went out singing and singing and ended up in Mathura, Krishna's birthplace. Her husband, the king, loved her very much and would not take part in troubling or harassing her. He searched round and round for Mira, and when he went to Mathura, he found her sitting in a temple, singing for Krishna. He bowed down to her. Then Mira's mother-in-law and sister-in-law also came, and they, too, bowed down. Mira was absorbed in Krishna. The world did not exist for her. She saw Krishna in everything, Krishna and nothing else. This is longing for God. One becomes mad after God.
Mira was devoted to Lord Krishna. Her devotion was like a fiancee of Lord Krishna (one of nine type of Bhakti) and got liberation. Anyone following any one of nine type of Bhakti can get liberation.
