The fourth chapter of "Brihadaranyaka Upanishad" starts as a dialogue between King Janaka and Yajnavalka. It explores various aspects of the "Soul exists" theory, its phenomenal manifestations, and its philosophical implications on soteriology. The Upanishad, in the first brahmanam of fourth chapter, states that the soul manifests in human life in six forms: "Prajna" (consciousness), "Priyam" (love and the will to live), "Satyam" (reverence for truth, reality), "Ananta" (endlessness, curiosity for the eternal), "Ananda" (bliss, contentness), and "Sthiti" (the state of enduring steadfastness, calm perseverance).
