God Name in Assiah
The name AL is used in many senses. Its deepest sense is given by The Book of the Law. The excuse for writing it here is that 4 represents Jupiter, the highest possible manifestation of Deity.
Heaven of Assiah
TzDQ - Sphere of Jupiter
The Sphere of Jupiter: Tzedeq means righteousness; the inexorable law of Jupiter. The connection of this with the number 4 depends on the aspect of 4 as the square of 2, the limitation of the Dyad further fixed by self-multiplication, the introduction of a new dimension. 4 is thus a number of rigidity or materiality. Hence its ideal quality is inexorable righteousness.
Yet, in connection with this, remember that Chesed means Mercy and 4 is Daleth, the letter of Venus, Love. Consideration of this is very helpful in understanding the way in which a Sephirah combines widely diverse ideas.
Path of Wisdom
The Fourth Path is named Cohesive, or Receptacular Intelligence, and is so called because it contains all the holy powers, and from it emanate all the spiritual virtues with the most exalted essences: they emanate one from the other by the power of the primordial emanation, The Highest Crown.
