You already know what your work is. That is the Gītā's quiet claim, and it is harder to hear than any instruction about God or the soul. Krishna does not hand Arjuna a purpose from outside. He points at the one already there — born of his nature, visible in what he cannot stop doing, confirmed by the fact that another person's duty, even done beautifully, feels like wearing the wrong skin. These verses do not ask you to discover your purpose the way you discover a continent. They ask you to stop pretending you have not already found it. The work that is yours will not leave you alone. Do it. Do it sheltered in something larger than the result. That is where purpose stops being a question and becomes a practice.
