सुभाषितानि

–महाभारत

Mahabharat Shlok with hindi meaning

Only two types of people are happy in this world. One who are foolish/dull and the others who are very much intelligent and knowledgeable. All the other people in between these two limits are the only sufferers.

The foolish/dull people do not understand the problem (or cannot grasp the problems) and the intelligent people have the solution for it! And therefore it is only left for the people in between them to keep crying for the problem because having known what it is still they cannot envision the path for it’s complete eradication.
