Acharya Prashant explains the profound meaning of the twelfth and thirteenth verses of the third chapter of the Bhagavad Gita, focusing on the concept of 'Yajna' or sacrifice. He clarifies that Yajna is not merely a physical ritual involving fire and priests, but a lifelong process where one's entire life energy, time, and resources are offered as an oblation toward a higher purpose. This higher purpose is described as reaching the 'Devas' or deities, which symbolizes attaining one's highest potential, liberation, and inner divinity. Shri Krishna emphasizes that Yajna, charity, and penance are essential actions that should never be abandoned, as they connect an individual to their ultimate destiny. The speaker elaborates that living a life dedicated to this higher goal is the true worship of the deities. In this process, whatever remains after dedicating everything to the supreme goal is what one should consume for physical sustenance. This is referred to as eating the remnants of the sacrifice, which frees a person from all sins. Conversely, those who utilize their resources, intelligence, and energy solely for their own physical nourishment and sensory pleasures, without contributing to the higher cause, are described as thieves. Acharya Prashant stresses that using what belongs to the 'Yajna' for personal gratification is an act of theft and sin, as it diverts life's energy away from consciousness and toward mere bodily existence.
