Going Zen ~ Self knowledge & Self mastery

Knowledge frequently results
from knowing others,
but the man who is awakened,
has seen the uncarved block.
Others might be mastered by force,
but to master one’s self
requires the Tao.
He who has many material things,
may be described as rich,
but he who knows he has enough,
and is at one with the Tao,
might have enough of material things,
and have self-being as well.
Will-power may bring perseverance;
but to have tranquility is to endure,
being protected for all his days.
He whose ideas remain in the world,
is present for all time.
-Lao Tzu, Tao Te Ching

A translation of the above which I like the most out of those I found:

Intelligent people know others.
Enlightened people know themselves.

You can conquer others with power,
But it takes true strength to conquer yourself.

Ambitious people force their will on others,
But content people are already wealthy.

Prudent people will abide.
People unconquered by the idea of death will live long.
People who live according to their means last long.
