The 6th chapter of Chandogya Upanisad (Sama Veda) contains the famous Mahavakya ‘tat tvam asi’.
After Svetaketu asked his father to teach him, Udalaka tells his son Svetaketu ‘sad eva saumya idam agra asid ekam evadvitiyam’ … ‘…in the beginning all this was one non-dual existence alone’.
Please note –
A certain preparedness is required for self-knowledge. Before listening to the teachings of the upanishads, we suggest you begin with listening to an ‘Introduction to Vedanta’ and ‘Tattvabodha’ audio series – both of which will give the novice listener a greater insight into the Vision of Vedanta and the importance of following the traditional methodology of teaching.
