Only by conscientiously carrying out all instructions from Steiner could full success be reached.
"These lines are written in the hope that the introduction and development of biodynamic methods may be furthered my methodical instruction. It is only a beginning, for in spite of fifteen years of practical work, we are but standing on the borders of a new world of knowledge and of life." E.P. Dornach, 1938.
