Explanation
Krishna separates action-mechanism from conscious experience. Body, senses, mind, and nature create action patterns; the conscious self experiences their results.
Read the traditional commentary
Krishna now assigns roles with great precision. Nature (prakriti) is the cause of all doing — the production of the body and its instruments, and the whole machinery of action. The hands act, the mind plans, the senses operate, all powered by nature's energies. The purusha, the spirit, is not the doer at all.
Yet the spirit is the cause in the experiencing of pleasure and pain. Here is the subtle knot of bondage: consciousness, by identifying with nature's processes, takes on the experience of joy and sorrow that rightly belong to the field. The witness, forgetting itself, feels itself to be the sufferer and enjoyer.
This diagnosis is profoundly practical. Suffering arises not from events themselves but from the self's entanglement with the field. The way out is to remember our true nature as the unattached witness — present to all experience, but no longer claiming it as our personal burden.
