Lao Tzu : Tao Te Ching : A Book About the Way and the Power of the Way

One doesn’t write a summary about this book, one simply notes that this is an excellent and approachable translation by Ursula Le Guin, perhaps one includes a snippet that was enjoyed (#33):

Knowing other people is intelligence,

knowing yourself is wisdom.
Overcoming others takes strength,
overcoming yourself takes greatness.
Contentment is wealth.
Boldly pushing forward takes resolution.
Staying put keeps you in position.
To live till you die
is to live long enough.
