E-Y-R-M – ‘blind, disordered movement; turbulent passion; darkness’

It is always the root עור, containing the idea of ardour, of a vehement fire, literally as well as figuratively. Formed from the root אור, which presents the idea of luminous corporeity [light], it becomes its absolute opposite. The one is a tranquil action; the other, a turbulent passion: here, it is an harmonious movement; there it is a blind, disordered movement. In the above example, the sign of manifestation י, has replaced the sign of the mystery of nature, and in this way Moses has wished to show that this terrible mystery was unveiled in the eyes of universal man, Adam. (The Hebraic Tongue Restored, Fabré d’Olivet, p. 101-102)
