Overview
Tishyaraksha or Tissarakkhā (c. 3rd century BCE) was the last wife of the third Mauryan emperor, Ashoka. According to the Ashokavadana, she was responsible for blinding Ashoka's son and heir presumptive Kunala. She married Ashoka four years before his death. She was very jealous of the attention paid by Ashoka to the Bodhi-tree, and caused it to be killed by means of poisonous thorns.
Early life
It is believed that Tishyaraksha was possibly born in Gandhara region and was a favourite maid of Ashoka's chief empress, Asandhimitra, and after her mistress died, she went to Pataliputra becoming a great dancer and charmed Ashoka with her dance and beauty.
Kunala
It is also believed that due to the age difference between her and Ashoka, she was attracted towards Kunala, a son of Ashoka who was religious in nature. Kunala regarded Tishyaraksha as his mother due to her place in the Mauryan Empire at the time. After perceiving rejection from Kunala, Tishyaraksha turned so furious that she decided to blind him. It is believed that the eyes of Kunala were attractive and beautiful and that they had originally attracted Tishyaraksha to him..
Plot
When the Chandragupta Sabha led by Radhagupta (the then minister (Mahaamatya) of the Mauryan Empire) decided that Kunala would proceed to subjugate the revolt of Takshashila (Taxila), Tishyaraksha conceived a plot. The plot succeeded after the conquest by Kunala.
