清朝在金國時期在遼東一隅創業，西藏大喇嘛斡祿打兒罕囊素與白喇嘛師兄弟二人從東蒙古科爾沁投奔而來，創立了金國/清朝的藏傳佛教。囊素喇嘛在天命六年(1621)遷來三個月後就圓寂，故真正建立藏傳佛教的是白喇嘛。追溯起來，囊素喇嘛在1615-1617年間，就曾受聘自東蒙古至赫圖阿拉二次，為金國在其城的「東阜」所興建的「七大廟」nadan amba miyoo)裡面的佛廟開光傳法。金國英明汗非常敬重這位大喇嘛，在其圓寂後，因累年征伐，末立即建立塔寺，故先設一臨時小廟(天命七年)，後始建立正式的舍利寺塔(天聰四年七月)，均命白喇嘛主持供奉。清朝在白喇嘛的手上創立佛法僧三寶俱足的教團，藏傳佛教真正成立。 白喇嘛(Bay-a Ba lama, >B-a Lama, >Be Lama, ?-1637)除主持上述藏傳佛教開教的事業外，還承擔金國汗交付的一些政治外交事務，主要的任務包括與明國議和，負責看管在盛京三官廟的明國俘虜張春，並拉攏其為金國服務，以及參與對蒙古事務等等。他是喇嘛身分的重要政治人物，這是因時代局勢使然，這方面經驗或許對清朝後來統治西藏與蒙古的方策產生久遠影響。本文透過稽考白喇嘛的事跡，釐析大清帝國藏傳佛教創始期的具體情形與特點。

　　　　　When the Ch'ing Dynasty (the Aisin Gurun) was in the process of establishing itself in the area of Liao-tung, it was for the first time visited by two Tibetan lamas in the persons of Orlug Darqan Nangsu Lama and B-a Lama (Bay-a Ba Lama, >B-a Lama, >Be Lama, ?-1637). These two Lamas were masters of Tibetan Buddhism, and had a religious brotherhood relationship between them. They came from the Qorcin and co-founded Tibetan Buddhism in the Ch'ing Dynasty. The Nangsu Lama died three months after his arrival (between the 22nd day of the fifth month and the 22nd day of the eighth month of the sixth year of Abkai Fulingga / A. D. 1621), and the B-a Lama was to be regarded as the actual founder of Tibetan Buddhism in the Ch'ing Dynasty. Previously, and during the years of 1615-1617, the Nangsu Lama had already been invited twice to deliver a sermon at the 'nadan amba miyoo' in East Hetu-ala. This was because the Nangsu Lama was one of the Genggiyen Han's (Nurgaci's) friends. The Genggiyen Han had high respect for this great Lama and promised to build him a Sheli Tower (Buddhism Pagoda) in accordance with his will. This tower was to be consecrated by his younger religious brother ('emu sajin i deo'), the master B-a Lama. Because of the long-term war at that time, the tower and temple were not constructed immediately, instead only a small temple was first built for provisional use. Later at the instance of the B-a Lama, the tower and temple were finally built in the fourth year of the Sure Han (A. D. 1630), and the B-a Lama was appointed as the master of this temple. With the B-a Lama, the Ch'ing Dynasty started to have a religion which included the Buddha-dharma-sangha, which is to say that Tibetan Buddhism was founded within the Ch'ing Dynasty. This paper aims to look at the history and activities of the B-a Lama and their influence on the Ch'ing Dynasty in the course of establishing Tibetan Buddhism in the Aisin Gurun. Besides these activities of establishing Tibetan Buddhism, the B-a Lama was mainly responsible for political and diplomatic affairs of the Han Qayan/Huangdi). As an important political figure, the B-a Lama (1) conducted peace negotiations with the Ming Dynasty, (2) looked after the Daiming Gurun's capture of Chang Ch'un (1565-1641) who refused to surrender to the Daicing and urged him to serve for the Daicing at San-guan Miao in Mukden (Sheng-Jing), and (3) participated in national affairs concerning Mongolia. The Ch'ing Dynasty might have benefited from the B-a Lama's experiences with Tibet and Mongolia in working out its own policies to manage Tibet and Mongolia. When the B-a Lama died in 1637, he was buried in the Tower Garden of the orlug Darqan Nangsu Lama in Liao-yang. In brief, in the light of careful research of the B-a Lama's activities, this paper tries to convey the conditions and character of Tibetan Buddhism in the period of its first establishment in the Ch'ing Dynasty.
