Who is Yaldabaoth, Saklas, Samael?

" When Sophia saw what her desire had produced, it changed into the figure of a snake with the face of a lion. Its eyes were like flashing bolts of lightning. She cast it away from her, outside that realm so that none of the immortals would see it. She had produced it ignorantly.

She surrounded it with a bright cloud and put a throne in the middle of the cloud so that no one would see it except the holy spirit, who is called the mother of the living. She named her offspring Yaldabaoth.

YALDABAOTH’S WORLD ORDER

Yaldabaoth is the first ruler, who took great power from his mother. Then he left her and moved away from the place where he was born. He took control and created for himself other realms with luminous fire, which still exists. He mated with the mindlessness  in him and produced authorities for himself: "

"Humanity Begins

Then came a voice from the highest realms saying:
“The Man exists! And the Son of Man!”

Yaldabaoth, chief ruler, heard it
He thought it came from his mother
He did not know the true source of the voice:
The Holy Mother-Father
Perfect Providence
Image of the Invisible
Father of Everything
In whom everything has come to be.

The First Man
[This is the one who appeared to them.
He appeared in the form of a human being.]

All of the realm of the chief ruler quaked!
The foundations of the abyss moved!

He illuminated the waters above the world of matter,
His image shown in those waters.

All the demons and the first ruler together gazed up
Toward the underside of the newly shining waters.
Through that light they saw the Image in the waters.

Yaldabaoth said to his subordinate demons:
“Let’s create a man according to the image of God
And our own likeness
So that his image will illuminate us.”

""And he made a plan with his powers. He sent his angels to the daughters of men, that they might take some of them for themselves and raise offspring for their enjoyment. And at first they did not succeed. When they had no success, they gathered together again and they made a plan together. They created a counterfeit spirit, who resembles the Spirit who had descended, so as to pollute the souls through it. And the angels changed themselves in their likeness into the likeness of their mates (the daughters of men), filling them with the spirit of darkness, which they had mixed for them, and with evil. They brought gold and silver and a gift and copper and iron and metal and all kinds of things. And they steered the people who had followed them into great troubles, by leading them astray with many deceptions. They (the people) became old without having enjoyment. They died, not having found truth and without knowing the God of truth. And thus the whole creation became enslaved forever, from the foundation of the world until now. And they took women and begot children out of the darkness according to the likeness of their spirit. And they closed their hearts, and they hardened themselves through the hardness of the counterfeit spirit until now"

"Their chief is blind. Because of his power and his ignorance and his arrogance he said, with his power, “I am god; there is no other but me.”

When he said this, he sinned against all. This speech rose up to incorruptibility. Then there was a voice that came forth from incorruptibility, saying, “You are wrong, Samael,” that is, god of the blind.

His thoughts became blind. And having expelled his power—that is, the blasphemy he had spoken—he pursued it down to chaos and the abyss, his mother, at the instigation of Pistis Sophia. She established each of his offspring in conformity with its power, after the pattern of the realms that are above, for by starting from the invisible world the visible world was invented.

As incorruptibility looked down into the region of the waters, her image appeared in the waters, and the authorities of the darkness became enamored of her. But they could not lay hold of that image which had appeared to them in the waters, because of their weakness, since beings that merely have soul cannot lay hold of those that have spirit. For they were from below, while it was from above."

"Then shadow perceived there was something mightier than it, and felt envy; and when it had become pregnant of its own accord, suddenly it engendered jealousy. Since that day, the principle of jealousy amongst all the eternal realms and their worlds has been apparent. Now as for that jealousy, it was found to be an abortion without any spirit in it. Like a shadow, it came into existence in a vast watery substance. Then the bile that had come into being out of the shadow was thrown into a part of chaos. Since that day, a watery substance has been apparent. And what sank within it flowed away, being visible in chaos: as with a woman giving birth to a child - all her superfluities flow out; just so, matter came into being out of shadow, and was projected apart. And it did not depart from chaos; rather, matter was in chaos, being in a part of it.

And when these things had come to pass, then Pistis came and appeared over the matter of chaos, which had been expelled like an aborted fetus - since there was no spirit in it. For all of it (chaos) was limitless darkness and bottomless water. Now when Pistis saw what had resulted from her defect, she became disturbed. And the disturbance appeared, as a fearful product; it rushed to her in the chaos. She turned to it and blew into its face in the abyss, which is below all the heavens.

And when Pistis Sophia desired to cause the thing that had no spirit to be formed into a likeness and to rule over matter and over all her forces, there appeared for the first time a ruler, out of the waters, lion-like in appearance, androgynous, having great authority within him, and ignorant of whence he had come into being. Now when Pistis Sophia saw him moving about in the depth of the waters, she said to him, "Child, pass through to here," whose equivalent is 'yalda baoth'."
