Love
Love is of the utmost importance to us humans. Everybody not only needs love, but also should give others love.
As can be seen in the picture, "love is a lamp which is brighter in darker places." This is indeed true. People in darker places need more light than other people. Maybe even a dim light can give them much hope for a better life. Maybe just a thread of light will call forth their strength and courage to help them step out of their difficulties.
I can think of no better illustration of this idea than the following examples. (Numerous examples can be given easily, but these will suffice For instance when someone is starving to death, just a little food and water from you may save his(her) life. Again, when a little girl in a poor rural area drops out of school because of poverty, just a small sum of money from you may support her t o finish school and change her life. In these circumstances you have given love which is like a lamp in a dark place where light is most needed.
To sum up, we should offer our help to all the needed. We expect to get love from others and we also give love to others. So when you see someone in difficulty or in distress and in need of help, don't hesitate to give your love to him (her). I believe that the relationship between people will be harmonious and our society will be a better place for us to live in.
