Or, he who knows contentment is rich. Feeling content is a key issue in the Tao Te Ching. It is interesting, perhaps even illuminating, to consider what being content means. I find that the Chinese characters are unique in their ability to convey meaning. The Chinese word for content is:

知足 zhizu = be content with one's lot.

Breaking this down further give us this:

知 zhi = know; realize; be aware of
足 zu = foot; leg; sufficient; enough; full

‘Know enough’; it is so simple, and yet...

One of the more ironic aspects of Taoism, or any other path, is that we are always able to ‘think’ more than we are able to ‘know’. To simply ‘know enough’, rather than continually seeking more and more in our wish to ‘know enough’ would resolve 99.99% of our life’s angst.
