the real teaching defies words but it cannot defy the heart. If there were a language of the heart, it could be said through it. But the heart has no language, silence is the only language of the heart.
When the heart is silent, it says something; when the mind is silent, it says nothing. Words are the vehicle of the mind. No words, silence, is the vehicle of the heart. Silence is a language without words, but one has to learn it. Just as one has to learn the languages of the mind, one has to learn the language of the heart: how to be silent, how to be wordless, how to be without a mind, how to be a no-mind.
When the mind stops functioning, immediately the whole energy moves towards the heart. When the mind is not functioning the heart functions; when the heart functions, only then can something be taught to you. The real teaching can be taught through the heart. You MUST be near the heart.
The nearer you are, the more capable you become of understanding the silence.
