In the case of oak bark, calcium as an alkaline earth metal does stand in the foreground. But what is decisive for its function is the structure in which the calcium is present in the bark of the oak in the form of calcium oxalate. In passing through the life processes of the oak, it forms itself as the product of a flowering process that has been prematurely discharged into the bark and has run its course to completion. The calcium oxalate receives its «structure» (form) as a whole through the essential nature of the oak, and in particular through the sulphuric working of oxalic acid. Gunter Gebhard adds to this: «The oak, as a Mars-/iron-being, has its deeper relationship to the I, to the sphere behind the cosmos, where the spiritual archetypes also reveal themselves to the supersensible researcher. Calcium draws all the astral into itself; that form in the physical is possible at all has its ground in the astral, while how form shows itself is grounded in the I (in the idea), which works through the astral. The calcium oxalate of the oak draws
