If you understand the matter of real knowledge 

Then everything is understandable. As long as a man does not make a mistake. Till then real knowledge is not attained. That alone is called lack of knowledge. Knowledge has many dimensions. The whole life of man is for knowledge only. Even until there is real knowledge. Till then man does not even know by earning anything. Knowledge is necessary everywhere in life. Man suffers from any subject matter only till then. Until we face reality. While walking on his path, man also does struggles. Man works hard. Man also makes use of his conscience. Man thinks too. Man understands. Man keeps on moving forward on his life path, opening the layers of his dimension one by one. Slowly adding the curry of knowledge to his life, he moves towards maturity. As knowledge increases. In the same way, all lack goes away. Sorrow goes away. The mistake ends. Then man matures. He is knowledgeable. That's why sorrow is nothing but lack of knowledge.
