Sri Jnanadev or Jnaneshwar, Poet and yogi, Jnani and Bhakta, was on this earth for about twenty years, nearly seven hundred years ago. His brief life was a divine event. The Bhagavad Gita embodies the essence of the Vedic Religion within a short compass and in the most popular form. That glorious dialogue between Nara and Narayana, Arjuna and Sri Krishna, is aptly described as Jnanamaya Pradipa - The Light of Knowledge.
Including Introduction to the study of Upanishads by SRI VIDYARANYA, and The Atharvana Upanishads: Amritabindy, Kaivalya. The Human being is not what he seems to be. He is not one person but five-fold, one covering another. The outermost person has to journey within to his inmost Self and return to the surface a new being altogether, according to the Taittiriya Upanishad. The high importance of this classical Upanishad as exclusively treating among other things, of the five kosas (sheaths of the Self) cannot be over-emphasised.
A great poem in World Literature, Dakshinamurti Stotra reveals the Poet and the Mystic in Sri Sankaracharya in unison at the highest altitude of his being. The four sons of Brahma born on his mind - MANASA PUTRAS - declined to continue the line of creation. Intent on returning to the Source they found themselves in the Presence of Siva as janana - Dakshinamurti in a blissful inner state of "Knowledge by identity". The thin veil over their eyes dropped as they, along with other sages, gazed at the luminous Silence. The perfect teaching was given and received in Silence.
