In plain words
He is deluded into thinking he should always have joy. This is impossible. Only when there is sorrow does joy have value. Only when there is hardship does happiness have value. Only when you have come walking through the sun does the shade of a tree have its value. In the same way, of those who ask why man should have hardships, why he should have sorrows, it can be said that they have no commonsense. In today's system of education, commonsense and general knowledge, both have grown scarce. If there were no hunger at all, who would long for food? If there were no heat, who would buy an air conditioner? Only the person who has clearly recognised the difference between these two clearly understands this matter of hardship and happiness.
Whether in the spiritual field, the physical field or the worldly field, in any field at all, it is through hardships alone that a man's fame and standing reach a high level. For the sake of Satya he went on meeting many hardships. Whatever may happen, I will not give up Satya. To protect Satya he lost his wife and child. To uphold Satya he lost even his kingdom. In the end he himself became a slave. Because he went through so many hardships, sorrows, griefs and disgraces, he was able to win the lasting name Satya-Hariścandra. Otherwise only the name Hariścandra would have remained to him. Through the very suffering he bore, he was able all along to uphold Satya, for whose sake he had lost everything. This is determination. This firmness must surge in man. Whatever hardships and losses and sorrows may pursue him, he must count none of them and offer even the body to reach his goal. This is the natural mark of the search for Satya. Only in hardships does the value of happiness become known. You all know it. A little boy. A boy of five years, Prahlāda. He went on contemplating Nārāyaṇa ceaselessly, longing for God. His own father went on putting him through many hardships. In the end he even resolved to take his life. He melted and moved the heart of a father so hard-hearted, and went on to win the victory. It is only because he went through so many kinds of hardship that Prahlāda was able to earn lasting fame. He did not give in to hardships. He went on mastering the hardships.
