Yasa was a bhikkhu during the time of Gautama Buddha. He was the sixth bhikkhu in the Buddha's sangha and was the sixth to achieve arahanthood. Yasa lived in the 6th century BCE in what is now Uttar Pradesh and Bihar in northern India. Yasa was raised in Varanasi in a life of luxury. His father was wealthy. The family home was full of servants, musicians and dancers who catered for the family's needs and entertainment. One day, when he had become a young man, Yasa awoke early and saw his female servants and entertainers asleep in a repulsive state. Disgusted by the spectacle, Yasa realised the vanity of worldly life, and left the family home muttering “Distressed am I, oppressed am I” and journeyed in the direction of Isipatana where the Buddha was temporarily residing after his first five bhikkhus had attained arahantship.

When the millionaire saw the Buddha and asked him if he had seen Yasa, the Buddha asked him to sit down, and then delivered a dharma talk. After this Yasa's father became the first to take refuge in the Triple Gems, the Buddha, Dharma and Sangha. Yasa, who was in the vicinity and had heard the talk given to his father, became an arahant. After father and son were reunited, the father invited the Buddha and the Sangha to his home for alms on the following day. The Buddha then ordained Yasa. The Buddha and his six arahants visited the home of Yasa the following day. Yasa's mother and his former wife thus became the first two female
