There is happiness and sorrow, happiness and prosperity, joy and pain in human life. At every stage of life, help from others is needed. Some are rich, some are poor; some are strong, some are weak. When the rich help the poor, then equality and peace are established in the society. Standing by the sick, helping the needy and helping those in danger is the true identity of humanity.
If people live only for themselves, then injustice and discrimination are created in the society. But when people think of others, then love, peace and justice are established in the society. In history, we see that countless great people have dedicated their lives for the welfare of humanity.
