From a scientific point of view I shall say that speech is the breath of breath. In the Vedanta breath is called prana, which is life. It may be said that breath is the chain that links body, heart and soul together, and is so important that the body - so loved and cared for, kept in palaces, its slightest cold or cough treated by doctors and medicines - is of no more use and cannot be kept anymore when the breath is gone. Speaking being the breach of breath means that, when one is speaking, one takes ten breaths in the time which would be normal for one breath. One says, "Where are you going?", and for these four words one takes three breaths.
