Acharya Prashant explains the deeper spiritual meaning of the twelfth and thirteenth verses of the third chapter of the Bhagavad Gita. He clarifies that 'Yajna' (sacrifice) does not refer to a physical ritual involving fire and priests, but rather to the transformation of one's entire life into a continuous offering. Shri Krishna emphasizes that one must dedicate all their energy, time, and resources toward their ultimate destiny and liberation, which is represented by the 'Devas' (deities). This act of offering everything to reach the highest state of consciousness is the true essence of Yajna.
