The purpose of this study is to translate, analyze, and interpret《Byang Chub Sems Dpa'' Las Domg Po Ba''i Lam La ''Jug Pa Bstam Pa》（論入菩薩初學道）in which is selected from the writings of The Venerable Atisha. Atisha is the greatest contributor of a revival in Buddhism after the prosperous period of Tibetan. According to Tibetan historical records, before the prosperous period of Tibetan, Buddhism was seriously destroyed because of the destruction conducted by King Lang Darma（藏王朗達瑪）The temples were either demolished or closed. The Sangha were disintegrated and activities such as translation and studying of Sutra were completely stopped. Such a "dark period" spanned about two centuries. It was not until mid 10th century did the society became gradually settled down. However, the Tibetan Buddhist community held very different opinions toward the sequences and insight of studying Sutra. There were many disputes on the issue of blending mahayana sect and estoric (mantra) sect. By that time, The King of Tibetan asked Atisha to stop the chaos by translating sutra, giving speeches, writing, and teaching. The book《Byang Chub Sems Dpa'' Las Domg Po Ba''i Lam La ''Jug Pa Bstam Pa》was finally written under that twist of fate. The thesis of《Byang Chub Sems Dpa'' Las Domg Po Ba''i Lam La ''Jug Pa Bstam Pa》is to discuss the self-cultivation methods of a devoted Buddhist, who trained himself through mahayana caste, rising bodhicitta, searching for teachers, apprentice behavior, diet, sleep, protecting six senses, taking care of livestock, observing breath, cleaning excrement and body, decorating chapels, giving offerings, kneeling and praying, converted to Buddhism, confessing, reciting scripture of four refuges, analytical and stabilizing, the concept of origin and emptiness, donating, how to maintain one''s mind, how many times to practice meditation daily, how to get rid of bad habits, and transference of merits to others etc. in daily life. These are ways to instruct beginners to train themselves from ordinary people to Buddha. Moreover, the book elaborates Atisha''s thoughts and practice of Buddhism. This study aims to discuss the insight of Atisha''s work.
