But what is of particular importance for the modern anthroposophist is the gaining of conviction with regard to reincarnation and karma. The way in which men gain this conviction, how they succeed in spreading the thought of reincarnation and karma — it is this that from now onwards will essentially transform modern life, will create new forms of life, an entirely new social life, of the kind that is necessary if human culture is not to decline but rise to a higher level. Experiences in the life of soul such as were described yesterday are, fundamentally speaking, within the reach of every modern man, and if only he has sufficient energy and tenacity of purpose he will certainly become inwardly convinced of the truth of reincarnation and karma. But the whole character of our present age is pitted against what must be the aim of true Anthroposophy.
