佛道心性論的互動是中國思想史的重大問題。本文著重從道家的道、自然、無為而無不為、靜觀、得意忘言思想對佛教的影響，強調道家為佛教尤其是禪宗提供了本體論、方法論和認識論的理論基礎；又從佛教的輪回果報、萬法皆空、心生萬法、明心見性思想對道教的影響，強調佛教對道教在轉變對人的形體、生命、人生理想的看法上起了巨大的推動作用，使之轉向於心性修養，而從揭示了中國佛道兩家心性論思想互動互補、交融會通的思想特色。

　　　　　The intermingling of the theory of mind and nature in Daoism and Buddhism is a big problem in the history of Chinese thought. This essay would like to proceed from the notions of Dao, Zi Ran, no exerted effort and everything gets done, silent observation and capturing the meaning and forgetting the words in philosophical Daoism and examine their influence on Buddhism. It would like to emphasize that philosophical Daoism, especially Zen, contributed largely to the basis of Buddhism's ontology, methodology and epistemology. From the perspective of religious Buddhism, I would like to take a look at transmigration and retribution, the dharmas are all empty, the dharmas are produced in the mind, and the enlightened mind sees the nature (明心見性), and their influence on religious Daoism. This in emphasizing that religious Buddhism had a great influence on religious Daoism in the realm of life ideals. In cultivating the mind and nature of man, Chinese Buddhism and Daoism drew from and complemented each other, creating a unique philosophical synthesis.
