Ohr

Ohr ("Light" Hebrew: אור‎; plural: Ohros/Ohrot "Lights" Hebrew: אורות‎) is the Kabbalistic representation of a monadic Intensification of Consciousness. Ohr emerges out of the limitless Ain Soph/Fabric of Consciousness and becomes the divine Ego from which emanates/flows all of Creation.

Like the word Monad, you may use capital "O" Ohr to refer to the original intensification that is god with a little "g" and you may use small "o" ohr may be used to refer to any, all, or even just one of the individual "lights" that adorn the glorious Tree
