What is the meaning of those who know do not speak but those who speak do not know?

What is the use of describing an orange to someone who has never tasted an orange? no Words can recreate the taste of 'orange', and to attempt such a feat is futile. Even if you are a poet, the Words you chose and the thought you convey is not the real experience, but infact only a distortion of it.

The wise man knows all beliefs are distortions of pure raw existence, and does not want to enslave your mind with more theologies, more dogmas, more barriers to experiencing the Tao. It is your birth right, and your very nature. Not by intellectualizing over it do we realize, but by exploring the silence.
