We seek happiness in our life. But a few men are endowed with it, while most others are not. As it is designed by nature, human life is a complex fabric of weal and woe. And it is largely full of sufferings, disappointments, and hardships. We learn more from our sufferings than from our happiness. Our soul gets purified by sufferings, as gold by fire. There are usually more tears than smiles. And tears touch us more deeply than laughter and fun. What touches the heart has, therefore, a more lasting and profound impression than purely momentary enjoyment. Thus the emotional appeal of a tragedy is far more deeper than that of a comedy. Shelley has caught this aspect of human life in immortal expression in a famous line of his poem. It is a paradox that though man loves happiness and shuns sorrows in his daily life, his sympatty goes with the sufferings of others. Thus songs or other creations of art which deal with a tragic theme evoke much quicker response from human hearts than the lighter subjects. Since sorrows and sufferings are the inevitable lot of human beings, their expression in song or verse have naturally a poignant sweetness for them.
