Ila ViAlul and Yesh MeAyin are different in two basic ways:
1) In Ila ViAlul the cause and effect are similar to each other, while in Ayin LiYesh they are dissimilar from each other.
2) In Ila Vialul the effect reveals its’ cause, and in Ayin and Yesh the yesh is hidden from the Ayin.
The KAV is similar to Ila ViAlul in the second way, but similar to Yesh MeAyin in the first.
The KAV is an altogether different character (or substance) from the Ain Sof in three ways:
A. The ohr is a Metzius.
B. the Ohr can come into Sefiros,
C. The Ohr has a relationship to space and spatial orientation (close and far).
