The life and death of human beings is a primary concern of Buddhism. Following the emergence of Tantric Buddhism,dhāra ī(similar to mantra) was in wide use in treating diseases and helping people out of suffering. Both Dunhuang printed edition of the Salvating Puerpera Dhāra ī and handwritten copies of Nanyue Wen and Fodingxin Guanshiyin Jing reflect Buddhist concerns about human reproduction and popular belief in Avalokite vara. The " Avalokite vara Bodhisattva Methods of Disease Treatment and Labor Inducement"from the apocryphal Fodingxin Guanshiyin Jing was widely circulated in China for a long time.
