It is not only grandeur and sublimity that indicate Universal Life, but smallness and commonplace do the same. A sage of old awakened to the faith[FN#151] when he heard a bell ring; another, when he looked at the peach blossom; another, when he heard the frogs croaking; and another, when he saw his own form reflected in a river. The minutest particles of dust form a world. The meanest grain of sand under our foot proclaims a divine law. Therefore Teu Tsz Jo-shi), pointing to a stone in front of his temple, said: "All the Buddhas of the past, the present, and the future are living therein."[FN#152] [FN#151] Both the Chinese and the Japanese history of Zen are full of such incidents.

In addition to these considerations, which mainly depend on indirect experience, we can have direct experience of life within us. In the first place, we experience that our life is not a bare mechanical motion or change, but is a spiritual, purposive, and self-directing force. In the second place, we directly experience that it knows, feels, and wills. In the third place, we experience that there exists some power unifying the intellectual, emotional, and volitional activities so as to make life uniform and rational. Lastly, we experience that there lies deeply rooted within us Enlightened Consciousness, which neither psychologists treat of nor philosophers believe in, but which Zen teachers expound with strong conviction. Enlightened Consciousness is, according to Zen, the centre of spiritual life. It is the mind of minds, and the consciousness of consciousness. It is the Universal Spirit awakened in the human mind. It is not the mind that feels joy or sorrow; nor is it the mind that reasons and infers; nor is it the mind that fancies and dreams; nor is it the mind that hopes and fears; nor is it the mind that distinguishes good from evil. It is Enlightened Consciousness that holds communion with Universal Spirit or Buddha, and realizes that individual lives are inseparably united, and of one and the same nature with Universal Life. It is always bright as a burnished mirror, and cannot be dimmed by doubt and ignorance. It is ever pure as a lotus flower, and cannot be polluted by the mud of evil and folly. Although all sentient beings are endowed with this Enlightened Consciousness, they are not aware of its existence, excepting men who can discover it by the practice of Meditation. Enlightened consciousness is often called Buddha-nature, as it is the real nature of Universal Spirit. Zen teachers compare it with a precious stone ever fresh and pure, even if it be buried in the heaps of dust. Its divine light can never be extinguished by doubt or fear, just as the sunlight cannot be destroyed by mist and cloud. Let us quote a Chinese Zen poet to see how Zen treats of it:[FN#153]
