Jyon gunga ke sain ko gunga hi pachichan
Tyon gyani ke sukh ko gyani habai so jan

The signs of a dumb can be understood by a dumb only
Likewise the pleasure of a knowledgeable can be known by a wise only.

Kabir is talking regarding language of Silence.

Silence is a profound language. Real communication happens in silence. When you become silent, God talks to you. You are talking with God without words because he knows no language. Silence is his language. Silence is the language of existence. We are disconnected with existence. The more silent you become, the more you are in tune with the whole.

Can silence be heard and understood?
Only silence can be heard and understood. Words can be heard but only superficially, and can be understood—but only intellectually. Silence is heard existentially and is understood from your innermost being. It is a total understanding.

The society is against it, because if you can hear silence you will not be a part of the crowd mind, of the collective mind. You will become an individual immediately. And an individual is a danger to the state, to the church, to the society. An individual is always dangerous, because an individual is nothing but rebellion. His very presence is a risk for all the vested interests, for the establishment. The establishment wants you to be obedient: he wants you to understand the orders. The establishment wants you to be slaves, servants—efficient, of course, but not too intelligent; just intellectual, not intelligent.

Silence is the explosion of intelligence. Silence means: inside you, you are just spaciousness, uncluttered spaciousness. Silence means you have put aside the whole furniture of the mind—the thoughts, the desires, the memories, the fantasies, the dreams, you have all pushed aside. You are just looking into existence directly, immediately. You are in contact with existence without anything in between you and existence. That is silence.

And to be in tune with existence even for a single moment—is enough to make you aware of many things. One is that you, are deathless, and the person who is deathless cannot be forced to be a slave. He would rather like to die than to become a slave. He would rather like to risk everything than to risk his freedom because death means nothing to him….
