In our life， joy and sorrow are like shadows that follow and go along with us。 Sometimes we are in joy。 Sometimes we are in sorrow。 At times we cannot tell joy from sorrow。

What is joy? In the nature that is going on forever， joy is a driving power， which pushes the world forward。 A joyful person has a sound mind and lives a happy life。 He takes part in good activities and shares the joy with his fellows in the cause。 It can be said that the joyful person is satisfied from being kind to others。

Sorrow is often self-sought①。 The desire for power adds to one"s sorrow。 The desire for power goes side by side with the desire for fame and wealth。 When the desire for power and fame and wealth is out of balance② with reality， it becomes the root of sorrow。 Besides， envy， revenge ③ and vanity④ are also sources of sorrow。 The three evils⑤ exist in man"s imagination⑥。 People suffer from them without knowing。

To be happy one must get free from sorrow led by desire and imagination。
