If you wish to dissociate the Divine light from the entity (the red color), and analyze it on its own, without the enclothing in the entity, this is already part of the third mode, i.e., form abstracted from substance, which is subject to errors, as stated above. For this reason, such an approach is strictly forbidden when studying the upper worlds, and no true Kabbalist would engage in it, and certainly not the authors of the Zohar. This is even more the case with regard to the “essence” of a detail in Beria, as we have no fundamental grasp even of the essences of corporeal entities,18That is, essences of corporeal entities of the levels, below Beria. much less the spiritual ones.
