You thus have four modes before you: a) the vessel of Beria, which is the mystical meaning of the red color, and which is considered the entity, or substance of Beria; b) the enclothing of the Divine light in the vessel of Beria, which is the form in the entity; c) the Divine light, abstracted from the entity in Beria; d) the essence of the individual detail.
The first principle has thus been thoroughly explained – that not a single word in the entire Zohar refers to the third and fourth modes; it deals solely with the first and second modes.
