A few more lines from Zhuang Zhou constructing a three dimensional model of what is possible within the Taoist course of practice. A “true” man or woman approaches what is possible for the individual in their place and time. 

Sometimes I have a restful night of sleep without haunting of dreams. But not often, even when I cannot remember what I dreamed in detail.

I often care about the flavor of my meal.

There is the reference to the breath, the link between proper comportment of the body and spiritual/emotional well being. I suspect the Zen admonition of concentrating upon the breath is taken from this and other Taoist verses.

This description of an optimized person, male and female is projected into the past, in ancient times. The time frame is a literary convention, to harken to a pure, simple, less conflicted time. The author’s point for the reader to consider – the personal value of day by day practice 

The true man/woman
in ancient times slept without dreaming
and woke without anguish.
He was unconcerned about the flavors.
His breathing came from deep within.
The breathing of the true man
comes from his heels,
when men in general breathe from their throats.

When men are defeated in argument
they throw up their words.
sunk in deep cravings,
they are shallow in the ways of heaven.

The true man/woman of ancient times
knew neither the love of life
nor the fear of death.
He entered life without delight
and left it without resistance.
Calmly he came and calmly he went.
He did not forget his beginning
nor did he probe into his end.

He accepted his life gladly
and forgetting the fear of death
he returned to the state before life.
He did not resist the Tao with the mind
nor attempt to assist heaven
by relying on man.

This is what is called a true man.
