Acharya Prashant explains that the ego typically acts for its own improvement and progress, setting goals based on personal gain. In contrast, Karma Yoga means that one's own betterment is not the objective; instead, righteousness is the goal. A Karma Yogi does what is appropriate without knowing or worrying about the outcome. While a common person focuses first on the result and then determines the path, a Karma Yogi focuses on the propriety of the action and completely forgets the result. The speaker notes that this approach is rare because human tendencies usually dictate goals, such as seeking a government job for comfort or responding to an attractive invitation, and then using the intellect only to find the path to that goal.
