A-R-TZ – ‘compressive, descending, densifying power’

…The primitive root אר, contains the united signs, almost always violent, of stable power and of continued movement proper…one adds the sign… צ, which expresses the term and end of all substance, one finds equally earth, that is to say, the element which is limited, figured, tactile, compressive, plastic, etc. (The Hebraic Tongue Restored, Fabré d’Olivet, p. 40-41)

…the set which tends more to manifest and to call forth an outer effect, and the set which is inwardly active, tending to remain as an inner experience. Then we have the essence of hashamayim and ha’aretz.” (Genesis, Rudolf Steiner, p. 10)
