Acharya Prashant explains that the ego's fear of death stems from its unfulfilled desires and the realization that its consumption of the world will eventually cease. He uses the analogy of a ticketless traveler hiding in a train's toilet to illustrate how the ego spends its life in fear and discomfort, never truly enjoying the fulfillment it seeks. He clarifies that the fulfillment the ego desires can only be attained through its own non-existence. True respect and satisfaction are found when the ego is set aside, as seen in the lives of sages and seers. Great things occur when there is no doer present to claim the results, yet the ego insists on its continuation to enjoy those results, thereby preventing greatness from manifesting.
