What does the Arcanum 3 announce to us?
Answers from the books of Samael Aun Weor
The number 3 is the EMPRESS, the Divine Light, the light itself; it is the “DIVINE MOTHER”. It relates to that part of Genesis which says: “AND GOD SAID: LET THERE BE LIGHT: AND THERE WAS LIGHT.” (Genesis 1.3) from the first day of creation.
It is also the number of the Third Logos, which dominates every form of creation; it is the rhythm of the Creator.
The CELESTIAL MOTHER in the material sphere signifies Material Output, and in the spiritual sphere means SPIRITUAL OUTPUT.
