If the cart is without a wheel then it is complete
If the sky is without the moon, then it is complete
If the bird is without a song, then it is complete
If the house is without a brick, then it is complete
If a doctor is without her letters, then she is complete
If an album is without a stamp, then it is complete
For, as said Mencius, "All things are already complete in oneself"
All one needs is to "examine oneself and be absolutely real.
Only then will there be great joy!"
*Mencius or Mengzi (372-289 bce) Chinese philosopher who has often been described as the "second Sage", that is after only Confucius himself. (Wikipedia)
