Pradyumna: "Those who are demoniac do not know what is to be done and what is not be done."
Prabhupāda: That is the first qualification of the demons. They do not know what is right doing and what is wrong doing. Suppose we, just like we restrict anyone who comes to our camp to become our student, we restrict that "You should not do this" or "You should do this." Anywhere, if you go to a physician, he'll say also that "You shall do this." Some "do's" and some "do not's." So the asuras, they do not know, because they have no direction, they do not know what are the "do's" and what are the "do not's." This is the first qualification of the asuras. They do not know. Because they do not like to take lesson from superior. They manufacture their own lesson.
