Manifestations of Karma

Why do people experience such different circumstances in life? What is the meaning of diseases, accidents, and natural disasters? We create our own karma, says Steiner; we lay the foundation in one incarnation for the next. We cannot find the whole pattern in one earthly life, but must look at many lives. He suggests that, though we may be unaware of particular causes, just knowing our own karma is in the process of resolution can help us gain a sense of purpose in our present lives.
