Acharya Prashant explains that action is an inevitable part of human existence. As long as one resides in a physical body, complete cessation of action is impossible. Even if one attempts to remain still or enters a state of unconsciousness, actions continue at subtle levels. He clarifies that the real question is not whether to act, but rather the quality, center, and direction of one's actions. This leads to the concept of 'Yajna' or sacrifice, which is defined as directing one's actions toward something higher and more excellent than oneself, rather than for personal gain or the fulfillment of desires. Ordinary actions are usually self-centered, aimed at strengthening the ego, whereas Yajna involves performing actions for the sake of the beloved Truth, without concern for the self. He further elaborates on the distinction between 'Sukha' (ordinary happiness) and 'Ananda' (bliss). Ordinary happiness is derived from achieving a goal, while bliss is found in the very first step taken toward the Truth, regardless of the destination. Acharya Prashant explains that 'Nishkama Karma' (selfless action) is synonymous with Yajna. While the ultimate Truth is formless and beyond imagination, humans use 'Devatas' (deities) as symbols of their highest potential to focus their devotion. He emphasizes that true worship requires total exclusivity; one cannot claim to love the Truth while remaining devoted to worldly attachments like power, money, or ego. True Yajna is not a ritualistic fire ceremony but an internal process of 'Swaha'—sacrificing everything changeable and ego-driven to realize the unchangeable Truth.
