Likewise upon your Earth, existing plants can be altered, grafted or improved but in a much more cumbersome and restricted way. Only in the spiritual domain is there evidence of similar perfection in humans on other planets too, as for instance the fruits of poetic imagination, whether in the conceptual language, as expressed in words or the language of creative arts, or through corresponding pictures with the aid of paints and other suitable materials; but most of all through the language of tones with which the composer can unfold supreme diversity, if his spirit is attuned in that field. But even this apparent perfection upon the planets is only a dim image of what is found in every thinkable subject upon the perfect sun planet. – The Natural Sun, Chapter 1, Paragraph 14
