Lao Tzu...

...the great Chinese philosopher wrote:

Decay and Renewal

Empty the self completely;
Embrace perfect peace.
The world will rise and move;
Watch it return to rest.
All the flourishing things
Will return to their source.

This return is peaceful;
It is the flow of nature,
An eternal decay and renewal.
Accepting this brings enlightenment,
Ignoring this brings misery.

Who accepts nature's flow becomes all-cherishing;
Being all-cherishing he becomes impartial;
Being impartial he becomes magnanimous;
Being magnanimous he becomes natural;
Being natural he becomes one with the Way;
Being one with the Way he becomes immortal:
Though his body will decay, the Way will not.

(tenet 16 of the Tao te Ching)
