Manfred Schimdt-Brabant, from his excellent short book, The Spiritual Tasks of the Homemaker
Schmidt-Brabant here refers to the mysteries of everyday life:
The mysterious process of cooking - which involves the breakdown and transformation of plants, animals, and minerals.
The materials of the home from different esoteric domains (the astral nature of wool, the ego nature of silk, the etheric nature of linen, etc.) and how their placement relative to each other creates a certain feeling (in other words a sort of Western esoteric feng shui).
The duties of cleaning the house - the encounters with dust and air and closed/openness. (“When you clean your living room, you release elemental beings,” Rudolf Steiner said. “When you read a lecture cycle, you release no elemental beings.”)
