In plain words
No hope of immortality comes from action, because action itself is born of ignorance. Liberation is caused by knowledge — so it needs nothing besides knowledge.
Close to the Sanskrit
There is no hope of immortality from that, from action, since it has ignorance as its cause. Because liberation has knowledge as its cause, it does not require anything other than that.
