Chumbo em Steiner (2007)

The mass we thus gain from the yarrow has an effect so quickening and so refreshing that if we now use the manure thus treated, just in the way manure is ordinarily used, we shall make good again much that would otherwise become a ruthless exploitation of the earth. We re-endow the manure with the power, so to quicken the earth that the more distant cosmic substances — silicic acid, lead, etc., which come to the earth in finest homoeopathic quantities — are caught up and received. (Steiner 2007:45)
