The Guru of all the Gurus giving the knowledge to his desciples sitting under the banyan tree with a smiling face and revealing the self through words employed in a special way to communicate and at same time not creating concepts or phylosophies but exactly unfolding the vision intended to be reached by the listener.This is "mauna vyakhya" . "Mouna" is silence "vyakhya" is its unfoldment.Unfolding the subject matter through silence means the words themself do not stick on to the listener . But having done the job they go away. Just as container is not to be taken for the content in it.So too the literal meaning of the words are negated and the actual vision is transfered in the process of teaching. This involves a methodology, which is transfered to the desciple during the process of teaching itself.This method of teaching is known a traditional way of handling the words and delevering the knowledge from Guru to shishya.This teacher to student (Guru to Shishya) is Guru Shishya parampara.The flow of knowledge without any break. Hence it is as fresh as it obtained in the begining so we can say it is ever fresh.The Lord is presented as ever young (yuva).what is taught by the Lord is also ever fresh. It is live because the conscious being is adressed here to make that individual to awake to see the self which is free in its own glory..!! OmTatSat
