Of the five practices of a Bodhisattva – saint practice, Brama practice, nature practice, child practice, and sickness practice – Nature practice is being aware of the true reality of things, as well as the beauty and wonder of nature. This is a state of perfect mindfulness being, as if at one with all of nature, which is the actual truth of reality. There is no real distinction between self and environment. … It is our false perception of reality that says this world is one of suffering and prevents us from realizing that in fact this world is the pure land of the Buddha.
