"All the various types of teachings and spiritual paths are related to the different capacities of understanding that different individuals have. There does not exist, from an absolute point of view, any teaching that is more perfect or effective than another. A teachings value lies solely in the inner awakening which an individual can arrive at through it. If a person benefits from a given teaching, for that person that teaching is the supreme path, because it is suited to his or her nature and capacities. There is no sense in trying to judge it as more or less elevated in relation to other paths to realization."

Chögyal Namkhai Norbu

S'eng Tsan, the author of those writings was both Chinese, and Buddhist. In fact, he was the third patriarch of Zen Buddhism. Maybe the "aura" you're speaking of is a flavor of Taoism, or an image of the Tao Te Ching that those verses evoke.

The Koan

Joshu once asked Nansen, "What is the Way?" Nansen answered, "Ordinary mind is the Way." "Then should we direct ourselves toward it or not?" asked Joshu. "If you direct yourself toward it, you go away from it," answered Nansen. Joshu continued, "If we do not try, how can we know that it is the Way?" Nansen replied, "The Way does not belong to knowing or not-knowing. Knowing is illusion; not-knowing is blankness. If you really attain to the Way of no-doubt, it is like the great void, so vast and boundless. How, then, can there be right and wrong in the Tao?" At these words, Joshu was suddenly enlightened.

"What we call the beginning is often the end, And
to make an end is to make a beginning. The end is
where we start from...

And the end of all our exploring will be to arrive
where we started, and know the place for the first
time. ”

~ T.S. Elliot

"By three methods we may learn wisdom: First, by
reflection, which is noblest; Second, by imitation,
which is easiest; and third by experience, which is
the bitterest.”

~ Confucius

Here the heart
May give a useful lesson to the head,
And learning wiser grow without his books...or google.

William Cowper (modified )

In my middle years I became fond of the Way
And made my home in the foothills of South Mountain.
When the spirit moves me I go off by myself
To see things that I alone must see.
I follow the stream to the source,
And sitting there, watch for the moment
When clouds rise up. Or I may meet a woodsman;
We talk and laugh and forget about going home.

WANG WEI

"Finish each day and be done with it. You have
done what you could. Some blunders and absurdities
no doubt crept in; forget them as soon as you can.
Tomorrow is a new day; begin it well and serenely
and with too high a spirit to be encumbered with
your old nonsense.”

~ Ralph Waldo Emerson

whenever I read a quote, I do so once with my inner voice...and once with the inner voice of a Loony Toons character.

"Ralph Waldo Emerson" usually goes well with Daffy Duck.

while "WANG WEI" is more of an Elmer Fudd.
