In plain words
Because of the momentum driving the body and mind, past karma might temporarily overpower knowledge—even though aimed at the real—and yield its own fruit, so that knowledge emerges when that karma is exhausted.
Close to the Sanskrit
Because of its capacity to initiate the body and the rest, action may overpower in you the knowledge whose object is the real and produce its result. At the end of that karma, knowledge would emerge.
