Instead of answering your question directly I shall quote from the Indian poet Tagore: “I slept and dreamt that life was joy/ I awoke and saw that life was service/I acted and behold, service was joy.” In fact, through my work I discover life, people, and everything which happens around us.
Those who show pity and are always ready to help during times of trouble are seldom the same ones who rejoice in our joy: when others are happy they have nothing to do, they become superfluous and lose their feeling of superiority, and so they easily show their displeasure.
