Khema was one of the two chief female disciples of Buddha (the other being Uppalavanna).

The name Khema means well-composed and she was quite beautiful. The nun belonged to the royal family of Magadha and was one of the chief queens of King Bimbisara.

She did not want to meet the Buddha as she knew he did not care much about beauty, and she was very self conscious about hers. She heard about the Buddha from her husband who encouraged her to hear his sermons and told her how beautiful Buddha's monastery was. Very interested in seeing beautiful things, decked out in royal splendor, she went to the monastery of Lord Buddha. There Buddha saw her approaching and created an exceptionally beautiful maiden by his side, whose beauty surpassed her own. Khema was captivated, seeing this, Buddha slowly aged the maiden :

Khema was finally willing to listen to Buddha, after his sermons, she attained full enlightenment, she became an arahant. With her husband's permission, she joined the order of nuns.

Ayya Khema (August 25, 1923 - November 2, 1997), a Buddhist teacher, was born as Ilse Kussel in Berlin, Germany, to Jewish parents. Khema escaped Nazis persecution during World War II. She eventually moved to the United States. After travelling in Asia she decided to become a Buddhist nun in Sri Lanka in 1979. She was very active in providing opportunities for women to practice Buddhism, founding several centers around the world. In 1987 she co-ordinated the first ever International Conference of Buddhist Nuns. Khema wrote over two dozen books in English and German, including her autobiography: I Give You My Life.

Ayya Khema was born in Berlin in 1923 to Jewish parents. In 1938, she escaped from Germany with two hundred other children and was taken to Glasgow, Scotland. Her parents went to China and, two years later Ayya Khema joined them in Shanghai. With the outbreak of the war, however, the family was put into a Japanese prisoner-of-war camp where her father died. She later married, had a son and a daughter, and now has four grandchildren.
