These four lectures were given at a Biodynamically inspired agricultural festival in the fall of 2019 in San Miguel de Allende in Mexico. The intent was to link the mineral, plant, animal and medicinal properties found in the high desert area of San Miguel. The background was the alchemical principles contained in the mandala of the temperaments, that was linked to the work of Rudolf Steiner in Biodynamics presented in the context of the particular destiny of Mexico for this work because of the appearance of the Virgin of Guadalupe. That appearance was presented as a symbol of the work to be done in tending the Earth in a sacred way.
