And, again, Transience holds its tyrannical sway not only over the material but over the spiritual world. At its touch Atman, or soul, is brought to nothing. By its call Devas, or celestial beings, are made to succumb to death. It follows, therefore, that to believe in Atman, eternal and unchanging, would be a whim of the ignorant. This is the doctrine called by the Hinayanists the Holy Truth of No-atman. If, as said, there could be nothing free from Transience, Constancy should be a gross mistake of the ignorant; if even gods have to die, Eternity should be no more than a stupid dream of the vulgar; if all phenomena be flowing and changing, there could be no constant noumena underlying them. It therefore follows that all things in the universe are empty and unreal. This is the doctrine called by the Hinayanists the Holy Truth of Unreality. Thus Hinayana Buddhism, starting from the doctrine of Transience, arrived at the pessimistic view of life in its extreme form. 8. Change as seen by Zen. Zen, like Hinayanism, does not deny the doctrine of Transience, but it has come to a view diametrically opposite to that of the Hindus. Transience for Zen simply means change. It is a form in which life manifests itself. Where there is life there is change or Transience. Where there is more change there is more vital activity. Suppose an absolutely changeless body: it must be absolutely lifeless. An eternally changeless life is equivalent to an eternally changeless death. Why do we value the morning glory, which fades in a few hours, more than an artificial glass flower, which endures hundreds of years? Why do we prefer an animal life, which passes away in a few scores of years, to a vegetable life, which can exist thousands of years? Why do we prize changing organism more than inorganic matter, unchanging and constant? If there be no change in the bright hues of a flower, it is as worthless as a stone. If there be no change in the song of a bird, it is as valueless as a whistling wind. If there be no change in trees and grass, they are utterly unsuitable to be planted in a garden. Now, then, what is the use of our life, if it stand still? As the water of a running stream is always fresh and wholesome because it does not stop for a moment, so life is ever fresh and new because it does not stand still, but rapidly moves on from parents to children, from children to grandchildren, from grandchildren to great-grandchildren, and flows on through generation after generation, renewing itself ceaselessly. We can never deny the existence of old age and death--nay, death is of capital importance for a continuation of life, because death carries away all the decaying organism in the way of life. But for it life would be choked up with organic rubbish. The only way of life's pushing itself onward or its renewing itself is its producing of the young and getting rid of the old. If there be no old age nor death, life is not life, but death.
