Premanand Maharaj Ji
What should I tell my child not to do on the phone so studies don't suffer?
No games, bad content or films on the phone
Children should not play games, watch bad things or watch dramas and films on the phone. If they do, those things come back in memory and their studies become weak.
Don't play games on it, don't watch bad things on it, don't watch dramas and films on it. If you watch them, your studies will become weak.
