In the east the works of Sa'di have been considered to be simple, educational, and at the same time uplifting. In India, Sa'adi's poem "Karima" is taught to children of nine and ten, and this work is not just a legend or an amusing story; it is like a seed sown in the heart of a child of that age, so that in time it may flourish and bring forth fruits of good thought and imagination. Karima is a poem of thanksgiving. In it the first lesson Sa'di gives is how to be grateful, how to express gratitude, how to appreciate; and he gives the lesson of gratefulness and appreciation for everything in the world, for the kindness and love of the mother and father, of the friend and the companion, by teaching first of all gratefulness to God for all the blessings and benefits man receives. Sa'di was a lover of humor, and he was a very simple man.
