Be a good human being 

very good advice, 

all the great souls are saying the same thing again and again, since ages, 

till this moment, and the trend is that they will continue to say it for ages

but problems are persisting , 

may be, will persist ever.

that means 

man does not know how to be good

or does not want to be good

but how to be a good human being 

here masters shy away from this question 

i don’t not know why 

they do not know the answer?

or do not want to reveal?
