Tao Te Ching Chapter 70

My teachings are very easy to understand

and very easy to practice,

But no one can understand them and

no one can practice them.

In my words there is a principle.

In the affairs of men there is a system.

Because they know not these,

They also know me not.

Since there are few that know me,

Therefore I am distinguished.

Therefore the Sage wears a coarse cloth on top

And carries jade within his bosom.
