Susima started inciting Bindusara against Ashoka, who was then sent into exile by the emperor. Asoka went to Kalinga, where he met a fisherwoman named Kaurwaki. He fell in love with her and later, made Kaurwaki his second or third wife. Soon, the province of Ujjain started witnessing a violent uprising. Emperor Bindusara called back Ashoka from the exile and sent him to Ujjain. The prince was injured in the ensuing battle and was treated by Buddhist monks and nuns. It was in Ujjain that Asoka first came to know about the life and teachings of Buddha. In Ujjain, he also met Devi, his personal nurse, who later became his wife.
In the following year, Bindusura became seriously ill and was literally on his deathbed. A group of ministers, led by Radhagupta, called upon Ashoka to assume the crown. In the fight that followed his accession, Ashoka attacked Pataliputra, now Patna, and killed all his brothers, including Susima. After he became the King, Ashoka launched brutal assaults to expand his empire, which lasted for around eight years. Around this time, his Buddhist queen, Devi, gave birth to Prince Mahindra and Princess Sanghamitra.
