Lecture IX
All this, however, is different for the undines. It causes them no unpleasant sensations; but when the millions and millions of water-creatures which perish in the sea enter into the state of decomposition the sea becomes for the undines the most wonderful phosphorescent play of colours. It shines and glitters with every possible colour. Especially does the sea glitter for them, inwardly and outwardly, in every shade of blue, violet and green. The whole process of decomposition in the sea becomes a glimmering and gleaming of the darker colours up to the green. But these colours are realities for the undines, and one can see how, in this play of colours in the sea, they absorb the colours into themselves. They draw these colours into their own bodily nature. They become like them, they themselves become phosphorescent. And as they absorb the play of colours, as they themselves become phosphorescent, there arises in the undines something like a longing, an immense longing to rise upwards, to soar upwards. Upwards they soar, led by this longing, and with this longing they offer themselves to the beings of the higher hierarchies—to the angels, archangels and so on—as earthly sustenance; and in this sacrifice they find their bliss. Then within the higher hierarchies they live on further.
