“Sir, what does the soul produce through concentration of the body?”
“Through concentration of the body it purifies the modes of conduct; having purified [them], it purifies perfect conduct; having purified [it], it destroys the four portions of karma belonging to an omniscient one. Thereafter it becomes perfected, enlightened, liberated, completely unburdened, and puts an end to all suffering.”
