Rudolf Steiner:
If Anthroposophy remains simply a matter of theory and external science, it is only half of what it ought to be; it fulfills its true function only when it streams through souls as a veritable elixir of life and enables these souls to experience in depth the feelings that arise in a human being when he acquires some knowledge of the higher worlds. Death then ceases to appear as a destroyer of human and personal relationships. The gulf between life here on Earth and the life after death is bridged and many activities carried out with this in mind will develop. The dead will send their influences into life, the living their influences into the realm of the dead.
My wish is that your souls will feel more deeply that life is enriched, becomes fuller and more spiritual when everything is influenced by Anthroposophy. Only those who feel this have the right attitude to Anthroposophy. What is of prime importance is not the knowledge that man consists of physical body, etheric body, astral body, and ego, that he passes through many incarnations, that the Earth too has passed through the several incarnations of Old Saturn, Old Sun, and Old Moon, and so forth. The most important and essential need is to allow Anthroposophy to transform our lives in a way commensurate with the Earth's future. This feeling can never be experienced too deeply, nor can we bestir ourselves too often in this connection. The feelings we bear with us from these meetings and then move through life under the stimulus of the knowledge of the super-sensible worlds acquired here — these feelings are the really important element in anthroposophical life. Merely to have knowledge of Anthroposophy is not enough; knowledge and feeling must be combined. We must realize, however, how false it is to believe that without any understanding of the world we can do it justice. Leonardo da Vinci's saying is true: “Great love is the daughter of great understanding.” He who is not prepared to understand will not learn how to love.
It is in this sense that Anthroposophy should find entry into our souls, in order that from this influence which proceeds from our own being a stream of spirituality may find its way into Earth-evolution, creating harmony between spirit and matter. Life on the Earth will, it is true, continue to be materialistic — indeed outer life will become increasingly so — but as man moves over the Earth he will bear within his soul the realization of his connection with the higher worlds. Outwardly, earthly life will become more and more materialistic — that is the Earth's karma — but in the same measure, if Earth evolution is to reach its goal, souls must become inwardly more and more spiritual.
