The flowering beech has so complex a structure that it is difficult to number. But the seeds make everything clear. We have two seeds in every pod and the pod itself has a clear four-fold geometry. So Beech has numbers of two and four. The seeds themselves are modelled on the tetrahedron so they are three-sided and four-pointed. Four is traditionally associated with the earth, four cardinal directions, four seasons etc. So what does this say about Beech as a Bach essence? This emotional state is earth-bound and outward looking. Bach says we are critical of others and want to correct imperfections. But it is interesting to note which other essences number in fours: Mustard and Heather.
