The heritage of summer is that we are able now to generate the shining of thinking ourselves, in our inner life. It is not a passive receiving of thoughts, but an active giving birth to them, again and again, continually. It dawns on us that thinking is conceiving the meaning of the realities of life; that we form concepts that are taken from the source of strength of world spirit. But we have to form them actively, forcefully, inwardly. They shine as an inner fire glows - as the sun glows in summer. They will bear us through autumn and winter.To arouse powerfully for myselfThe shining of thinking in my inner life,Reading meaningfully what I have experiencedFrom world spirit's source of strength: Is heritage of summer,Is calm of autumn and also hope of winter.Sich selbst des Denkens LeuchtenIm Innern kraftvoll zu entfachen,Erlebtes sinnvoll deutendAus Weltengeistes Kräftequell,Ist mir nun Sommererbe,Ist Herbstesruhe und auch Winterhoffnung.
