The view of Zen on Pure Land could be grouped into three. The first type was the explanation from ”Mind-Nature Theory”. The second was negativism, thoroughly denying any real world inside or outside. The third was the view that Pure land could be mixed with Zen, even the supporters advocated ”Practice for both Zen and Pure Land”(禪淨雙修). These three kinds are termed discriminatingly as ”The Mind-Nature Theory of Mind-Only Pure Land”, ”The Negativism of None-Mind None-Buddha”, ”The Coherentism of while Mind is Buddha”. Because the Platform Sutra was a sutra of Chinese's own, the thought in this book were all Mind-Nature Theory, attributed to the first type. After Hui-neng, some disciples misled the meaning into none of Pure Land. They developed the attitude of blaming on Buddha. We attributed to the second type. The third type was the thought that had been coherent. It emphasized the function of mind that could unfold the Pure Land. The three types would rather be regarded as steps of Zen than difference. Also, the third type was a turn from first and toward pure land. If we follow the second type, it would shock the thought of Pure Land Sect. It was not appropriate. If we follow the third type, it would be some positive contribution for Pure Land Sect. We hope to reveal the positive meaning from the Platform Sutra for Pure Land.
