Listen to teachings about the Self from the Chandogya Upanishad. First, hear how Uddalaka teaches his son Svetaketu about the nature of the Self through the cutting of a fig seed and the melting of salt in water. Next, hear how Prajapati teaches Indra about the nature of the body, mind, state beyond waking and dreaming, and, finally, the unseen seer, unheard hearer, and un-understood understander.Tat tvam asi.
