To Leave suffering and attain bliss is the goal of learning and practicing Buddhism by a Buddhist.In order to help sentient beings to leave suffering and attain bliss,A Buddha with perfect bliss and wisdom made his vow to create his Pure Land. Master Yin Shun has broadly interpreted the meaning of a Pure Land .He indicated that the Pure Land Thought is an important doctrine in Buddhism,especially. in recent Buddhist history. The Pure Land does not only refer to the land of Western Utmost Happiness. The so called When the mind is pure, sentient beings are pure,"""" and """"When the mind is pure, the Buddha land is pure,""""has""""-righteously explain the root cause of the world. As for Pure Lands, most people will think of the Amida's west Pure Land, the Medicine Master Vaidurya Light Tathāgata's east Pure Land, the Maitreya Tuṣita's Pure Land, etc..-However from the view of a Buddhist learning process,we could say the Pure Land is one of the common ecpectation of all the sentient beings. In this thesis we focus on the research of the Pure Land Thought. We study the various theories of the Pure Land Thoughts, followed by the Yin Shun's Pure Land Thought. Based on these knowledge,we generalize the understanding of the foregoing west, the east, and the top Pure Land to all the Pure Lands in all directions. We conclude that the essence of the Pure Land is to leave suffering and attain bliss, and we may accomplish the idea of Humanistic Pure Land by applying the Pure Land Thought in humanistic.
