Acharya Prashant explains the profound meaning of sacrifice as described in the Mundaka Upanishad. He clarifies that true sacrifice is not merely the ritual of lighting a fire and offering clarified butter, which are only symbols; rather, it is the performance of selfless action. Drawing from the teachings of Shri Krishna to Arjun in the Gita, he emphasizes that one should perform all actions without desire for personal fruit. When a person acts for the highest goal rather than for themselves, their mind is elevated to a divine state, metaphorically described as being carried by sunbeams to the abode of Indra. This state of selfless action lightens the individual and provides liberation from the burden of the ego.
