All communication is in fact a communication in consciousness.
The ears hear only a body of sounds and the eyes see an expression on the face. When we hear by the mind, we understand the outer meaning. Human beings often use words to conceal rather than communicate the true intent.
We can also listen through the heart and touch some deeper chord hidden behind the sounds and words. We touch the world of feelings that push the words for expression and drive it towards its secret destination.
But there is a still deeper listening, the true ear that lies behind our ears or the Hearing behind our hearing as the Upanishad puts it. It is the hearing and listening that takes place in and through the soul. It brings with it the true understanding and along with it the gifts of harmony, beauty and peace and light, and makes communication a bridge between the one who speaks and the one who hears.
