Conversation extending to several years can be known in a trice in Silence, or in front of Silence - e.g., Dakshinamurti, and his four disciples

Ramana Maharishi:  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; the ‘I-thought’ is the root of all conversation. When one remains without thinking one understands another by means of the universal language of silence.  Silence is ever-speaking; it is a perennial flow of language; it is interrupted by speaking. These words obstruct that mute language. 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 in a trice in Silence, or in front of Silence - e.g., Dakshinamurti, and his four disciples. That is the highest and most effective language.
