। ॥ १८९ ॥
In plain words
Action lies in the agent's hands: he can do it, leave it undone, or do it some other way. Knowledge of what actually is, is not like that. It never depends on the doer.
Close to the Sanskrit
By an agent, action can be done, or not done, or even done otherwise; not so is knowledge of a real thing ever dependent on the agent.
