The wise man looks back into the past, and does not grieve over what is far off, nor rejoice over what is near; for he knows that time is without end.
LaoziMen are born soft and supple; dead, they are stiff and hard. Plants are born tender and pliant; dead, they are brittle and dry. Thus whoever is stiff and inflexible is a disciple of death. Whoever is soft and yielding is a disciple of life. The hard and stiff will be broken. The soft and supple will prevail.
Laozi
