Book excerpt: This classic text by Ehrenfried Pfeiffer contains the practical experience of the pioneers of biodynamic agriculture, who experimented on the basis of the indications given to them by Rudolf Steiner, who passed on this valuable practical experience to all of us. Only by conscientiously carrying out all instructions from Steiner could full success be reached. Originally published in 1938, this is still an important resource for the biodynamic farmer or gardener. "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." (Ehrenfried Pfeiffer, Dornach, 1938)
