Chandogya Upanishad Chapter 7

The seventh chapter of the Chandogya Upanishad opens as a conversation between Sanatkumara and Narada. Through 26 sections of the seventh chapter, the Upanishad presents, in the words of Sanatkumara, a hierarchy of progressive meditation, from outer worldly knowledge to inner worldly knowledge, from finite current knowledge to infinite Atman knowledge, as a step-wise journey to Self and infinite bliss.
