During the Tang dynasty (618–907), changes in political policies, the religious landscape, and gender relations opened the possibility for Daoist women to play an unprecedented role in religious and public life. Women, from imperial princesses to the daughters of commoner families, could be ordained as Daoist priestesses and become religious leaders, teachers, and practitioners in their own right. Some achieved remarkable accomplishments: one wrote and transmitted texts on meditation and inner cultivation; another, a physician, authored a treatise on therapeutic methods, medical theory, and longevity techniques. Priestess-poets composed major works, and talented priestess-artists produced stunning calligraphy.
