Lecture III

On this path, for example, an opposing force once again intervenes. The opposing force that intervenes can be well observed if you study, simply to take an example, the common birch, betula alba. Pursue very precisely the process that takes place from the root formation through the trunk formation, particularly the bark formation. Consider how, on the basis of everything that works together in the trunk and bark formation, there develops what later comes into manifestation in the leaf formation. This can be studied particularly well in a spiritual scientific way if the still-brownish young birch leaves are studied in the spring.
