In this final episode, Sri Madhusudan Sai explains more on the different levels of knowledge, and if used correctly, how they lead us to the ultimate liberation that comes from ātmavidyā - realising one's true divine nature as brahman. This realisation of "I am brahman" has to permeate every cell and become one's entire existence.
The episode also touches upon the role of brahmacarya, sannyasa, and the significance of pursuing spiritual wisdom instead of getting trapped in materialistic desires. It highlights how the upanishads provide clear answers to existential questions that other philosophies cannot.
