The Ten Sephiroth of the Tree of Life develop in every round; a Mahamanvantara (Great Cosmic Day) has seven rounds, we are in the fourth round, the terrestrial round.
The fall of this present humanity took place in Eden and Eden is in the vital/ethereal plane, the fourth dimension. We are the humanity of the fourth round. Beelzebub is from the first round.
In Beelzebub’s time, “All was of a mental matter; all of the human beings used Astral bodies... They ate, dressed, drank and enjoyed themselves like in this present time, because the Astral Body is an organism almost as dense as the physical. Thus, it was analogously constituted as the physical body...” - The Revolution of Beelzebub by Samael Aun Weor
"You have heard that it was said by them of old time, Thou shalt not commit adultery: But I say unto you, That whosoever looks on a woman to lust after her has committed adultery with her already in his heart." - Matthew 5: 27, 28
Fornication and adultery is committed in the 49 levels of the mind; this is why the Sephirah Daath, the Tree of Knowledge, is located underneath Kether, Chokmah Binah and above Chesed. Geburah and Tiphereth.
