Lecture XIII
First of all we must observe the precise manner in which the varieties of mistletoe (viscum) develop on the soil of other plants. But this is not the main factor under consideration. For the botanist, of course, the parasitism of such plants as mistletoe is the essential point. But for the study of the inter-relationships of extra-human nature to man, it is far more significant that the mistletoe as it grows on trees is compelled to follow a different yearly rhythm from that of other plants, its blossoms have been formed before the trees which are its hosts, begin to put forth their leaves in spring. Thus the mistletoe is a kind of winter blooming plant, protecting itself under the shelter of alien foliage, from the extremes of the summer sun's rays, or better, from the light workings of summer; there is something of an aristocratic attitude about the mistletoe. (See Diagram 24). The sun must be taken—in the sense of the XI lecture—as being the representative only of the light workings: but this subject forms a chapter of physics and does not interest us here; it is unfortunately impossible to avoid phrases introduced into our language by an incorrect conception of nature. The whole manner in which the mistletoe attaches itself to other plants in order to grow and thrive is the essential point: it acquires and appropriates particular forces which may be described as follows. Its nature is to oppose all the tendencies of the straight course taken by the organic forces, and to urge towards all that to which the straight course taken by the organic forces is opposed. Let us try to elucidate this by means of a rough sketch, (see Diagram 24) representing an area in the physical body of man which revolts against the whole access of the etheric forces, so that the latter are, as it were, dammed up and stopped and thus what appears to be a “neoplasm” is formed; and the mistletoe counteracts this “pocketing” which has been formed and draws the forces again to the area which they do not want to enter.
