the difference between Iod-Havah and Yahweh/Jahve in original hebrew

In the Old Testament, the name of Jehovah is applied to the Host of the Cosmocreators or divine Androgynes who created this Universe, rather than the original name Iod-Heve. - Pistis Sophia Unveiled by Samael Aun Weor

Jehovah, the Holy Spirit, guards the body of the Holy Spirit in ourselves. Jehovah was the highest Initiate from the Lunar epoch [past Mahamanvantara]. – Revolution of Beelzebub by Samael Aun Weor

We have the case of the Master Jehovah that sent his Bodhisattva to Chile. At the present time (1970), he is a young boy who is living foolishly. So, this Master is only waiting for the Bodhisattva to mature in order to penetrate within him. Jehovah is the Regent of the ancient Moon. He is a great Master that has been intentionally confused with Javhe, who is the chief of the Black Lodge. - Tarot and Kabbalah by Samael Aun Weor

A long time ago, in the profound night of the centuries, there in the continent of Mu or Lemuria, I knew Javhe, the fallen angel who was spoken of by Saturnine of Antioch.

Certainly, Javhe was a venerable Master of the White Brotherhood†, a glorious Angel from previous Mahamanvantaras.

I knew him; I saw him when he was a priest and a warrior among the people of Lemuria. Everyone loved, adored, and venerated him.

The Hierophants of the Purple Race granted him the high honor of using armor, crest, helmet, shield, and sword of pure gold.

This warrior-priest shone as a flame of gold within the thick, sunny jungle.

Upon his symbolic shield, Vulcan had engraved many prophecies and terrible warnings.

Woe! Woe! Woe! This man [Bodhisattva] committed the error of betraying the mysteries of Vulcan.

The Lucifers of that epoch who were floating in the atmosphere of the ancient continent Mu taught him Black Tantrism, the Maithuna with the ejaculation of the Ens Seminis.

What is most grave in this matter is that this man, who was so loved and venerated by all the world, allowed himself to be convinced and began to practice this type of pernicious Sexual Magic with certain women.

Therefore, it is clear that the igneous serpent of our magical powers descended through his medullar canal and was projected from his coccyx downwards, thus forming and developing in Javhe’s Astral Body the abominable Kundabuffer Organ.

This is how [the Bodhisattva of] this Angel fell, and through the ages became converted into a terribly perverse demon. - Gnostic Magic of the Runes by Samael Aun Weor

The human being is a triad of Body, Soul, and Spirit. The Soul is the mediator between the Spirit and the Body. A Soul is acquired and a Spirit IS.
The Innermost is the Highest Aspect within us; the Innermost is the Spirit.

The Testament of Learning states:

“Before the false dawn came over this earth, those who survived the hurricane and the storm gave praise to the Innermost, and to them appeared the heralds of the dawn.”

Thus, the Soul is between the terrestrial man and the Innermost; the Soul is dressed with an ultra-sensible, material body with which it travels through space. This ultra-sensible, material body is the Astral Body. Thus, the Astral Body has something of the human and something of the divine. - Major Mysteries by Samael Aun Weor
