How does this silent power work

Question: How does this silent power work?

Sri Ramana Maharshi: Language is only a medium for communicating one’s thoughts to another. It is called in only
after thoughts arise. Other thoughts arise after the "I"-thought
rises and so the "I"-thought is the root of all conversation. When one remains without thinking one understands another by menas of the universal language of silence.

Silence is ever speaking. It is a perennial flow of language,
which is interrupted by speaking. These words I am speaking obstruct that mute language. For example, there is electricity
flowing in a wire. With resistance to its passage, it glows as a lamp or revolves as a fan. In the wire it remains as electric
energy. Similarly also, silence is the eternal flow of language, obstructed by words.

What one fails to know by conversation extending to several
years can be known instantly in silence, or in front of silence. Dakshinamurti and his four disciples are a good example of
this. This is the highest and most effective language.
