To be helpful to people

 Only when you are enlightened, you can be helpful to other people.
 It has been previously said that being enlightened is different from understanding. Understanding is to becoming to know an explanation of a fact and being enlightened is that you can see the fact itself.
 It is very difficult to give people a definite help with only a similar understanding of what is happening to them. If you can see the problems people have, you can show them a sure way to help.
