Silica and Lime
Silica and limestone form strong themes within Rudolf Steiner’s mystery wisdom. Initiates of the past experienced silica’s connection to the formation of the plant imaginations in the body of the earth, while calcium with its desiring nature is connected with the breathing in of the animal forms into the earth. The plants in their selfless giving and the animals in their consuming desirous natures are connected to the silica and calcium gesture respectively, as question and answer. The stage of the earth described here by Steiner has an atmosphere of living substance, a protein albuminous substance, which through the activity of sulphur, finds its connection to the formative gestures of the mineral realm.
