Someone with a mind which is just starting something has very many options about how to proceed and sometimes they are trapped because there are so many directions to go that they can't decide on any. Someone with a mind who has studied something for a long time has few options about how to proceed and sometimes they are trapped because there seems to be only one way to go. Someone with a mind who is a master has no options I think and therefore they can do anything that they want or don't want so they are not trapped and they fly.
