本文主要在探討佛學中的「不二」概念，討論如何以「不二」看待人與自然之關係，以及個人應當以何種方式，將自身融入自然這個大存有之中。人與自然的關係，是一個「不二」的整體，在教育方面，學習體會人與自然的合一，讓個人心靈與自然相應，是靈性教育的重要方向。本文首先說明當前人與自然之關係，以及當中隱含的問題；接著探討佛法對於自然的看法，以及當中的生態智慧，並依據佛法的非二分哲學，闡釋「人與自然一體」之要義。最後，作者針對靈性教育提出一些想法，思考如何藉由人與自然的不二關係，提升個人靈性發展，此即回歸到我們心靈的「自然」。本文所指的「自然」，不只是物質層面的自然，也擴及精神層面無形的自然。

This article discusses the Buddhist concept of “nonduality.” This concept can be applied for considering the relationship between humans and nature, and for thinking the integration of the self into nature. Humans and nature are incorporated into a oneness. Realizing this truth can help learners to connect their spirituality with nature, which is vital for practicing spiritual education. In this article, descriptions are given of the present state of human-nature relations and the problems it engenders. Next, Buddhist perspectives on nature and ecological wisdom are explained. The significance of oneness between humans and nature is explored by means of nondualist philosophy. Finally, some thoughts regarding spiritual education, particularly with regard to improving individual spiritual development and returning to a natural condition of human spirituality, are developed in accordance with the nondualist perspective. “Nature” in this article refers not only to material nature, but also to nature in its spiritual aspect.
