Siha was born at Vesali as the daughter of General Siha's sister. She was named after her maternal uncle. When she grew up, she heard the Master teaching the Norm to her maternal uncle and became a believer. She was permitted by her parents to enter the order.
For seven years she could not acquire insight as her mind became always inclined to objects of external charm. Then she intended to die. She took a noose, hung it round the bough of a tree and fastened it round her neck. Thus she succeeded in impelling her mind to insight which grew within and she won Arahantship. She then took off the rope from her neck and went back to her hermitage.
