Throughout all our lives,
We have discovered one at a time, or all at once.
Happiness and joy, sorrow and tears.
Heedless butterfly, who only knows laughter and flowers,
Gloomy caterpillar, who gets stuck in mud and tears.
But the one, like the other, are only two aspects of the same being.
The one would not exist without the other.
(Zen Philosophy ~ Seng - T'san)
