 As there is some debate about whether the bhikkhuni lineage (in the more expansive Vinaya forms) was transmitted to Tibet, the status and future of female Buddhist clergy in this tradition is sometimes disputed by strict adherents to the Theravadan style.Some Mahayana sects, notably in the United States (such as San Francisco Zen Center) are working to reconstruct the female branches of what they consider a common, interwoven lineage.The diversity of Buddhist traditions makes it difficult to generalize about Buddhist clergy.
