If one would ask what is the cause of all the misery in life, the answer would be that there is one cause only and that is the limitation of life. Misery, pain, or sorrow of any kind comes from limitation. There may be poverty or illness or disappointment, but it is all limitation; and this has been found out by all the prophets and teachers of humanity. When Buddha was young he saw that there was great pain in the world, and his first thought was to find out what was behind it; and so it has been with all the great teachers. They all wanted to solve this one question, to find out what is the cause of all misery.
