In Krishna’s final chapter of the Bhagavad Gita there are a number of places where Vaishnava commentators consider the book could have ended. After the first of his possible endings, Krishna wants to make sure Arjuna—and we readers—have understood his hope for all souls. Thus he summarizes his ultimate instruction, as the powerful conclusion.
The idea that his book—it is “his” book after all!—of perennial wisdom has a conclusion is often surprising to the casual reader looking for generic spiritual wisdom to add to their lives or personal agenda. We conditioned souls have a very ego-centric view of the world and any information or knowledge we come into contact with. Sometimes people like the Gita because they think it recommends many paths and one can choose one that appeals to them according to their personal criterion.
