II. How Karma Works
His advance through ever new incarnations signifies a higher development of the human spirit. This higher development comes to expression in the fact that the world in which the incarnations of the spirit take place is comprehended in increasing measure by this spirit. This world, however, comprises the incarnations themselves. In regard to the latter, too, the spirit gradually passes from a state of unconsciousness to one of consciousness. On the path of evolution there lies the point from which the human being is able to look back upon his successive incarnations with full consciousness.—This is a thought at which it is easy to mock; and it is easy to criticise it negatively. But whoever does this has no idea of the nature of such truths. And derision as well as criticism place themselves like a dragon in front of the portal of the sanctuary within which we may attain knowledge of these truths. For it is self-evident that truths, the realization of which lies for the human being in the future, cannot be found as facts in the present. There is only one way of convincing oneself of their reality: namely, to make every effort possible to attain this reality.
