It is the natural right of every human being to be happy to escape all the miseries of life. Happiness is the normal condition, as natural as the landscapes and the seasons. It is unnatural to suffer and it is only because of our ignorance that we do suffer. Happiness is the product of wisdom. To attain perfect wisdom, to comprehend fully the purpose of life, to realize completely the relationship of human beings to each other, is to put an end to all suffering, to escape every ill and evil that afflicts us. Perfect wisdom is un-shadowed joy.
Why do we suffer in life? Because in the scheme of nature we are being forced forward in evolution and we lack the spiritual illumination that alone can light the way and enable us to move safely among the obstacles that lie before us. Usually we do not even see or suspect the presence of trouble until it suddenly leaps upon us like a concealed tiger. One day our family circle is complete and happy. A week later death has come and gone and joy is replaced with agony.
Today we have a friend. Tomorrow he will be an enemy and we do not know why. A little while ago we had wealth and all material luxuries.
