Nan-in, a Japanese master during the Meiji era (1868-1912), received a university professor who came to inquire about Zen.

A newborn is soft and tender,
A crone, hard and stiff.

In death, withered and dry.
So softness and tenderness are attributes of life,
And hardness and stiffness, attributes of death.
