Acharya Prashant explains that the Vedantic approach is fundamentally an inquiry into self-knowledge, asking the question 'Who am I?'. Because it is difficult to directly understand one's real identity, karma serves as a proxy or surrogate to understand the doer. While the term karma is popular globally, its true meaning is often misunderstood. He clarifies that reincarnation does not happen at the level of the individual person; rather, it is the underlying tendencies or mother-tendencies that take birth repeatedly, much like waves in an ocean. The individual person dies and does not return, but the seeking of fulfillment through physical existence continues through these tendencies.
