“Sir, what does the soul produce through endowment with conduct?”
“Through endowment with conduct it produces the state of immovable steadiness; and the homeless mendicant, having entered upon immovable steadiness, 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.”
