Energy(Invincible Power / Thought) ---> Observer(Sophia / Yaldabaoth) ---> Mass(Matter / Universe)

"And because of the invincible power within her, her thought was not an idle thought. Something came out of her that was imperfect and different in appearance from her, for she had produced it without her partner. It did not resemble its mother and was misshapen.

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."

"Energy and mass are interchangeable (E=mc2). Since thoughts are energy signals, the energy transmitting a thought therefore has mass. The ions and molecules encoding the energetic signal have mass too. But can we actually calculate the weight of a single thought? Certainly it would be an infinitesimally tiny number. But not zero."

"“Opening his eyes he saw a vast quantity of endless matter, and he turned arrogant, saying, ‘I am god, and there is no one but me.’

“When he said this, he sinned against all. And a voice came from above the realm of absolute power, saying, ‘You are wrong, Samael,’ that is, god of the blind.

“And he said, ‘If any other thing exists before me, let it become visible to me!’ Immediately Sophia pointed her finger and introduced light into matter, and she pursued it down to the region of chaos. And she returned up to her light. Once again darkness returned to matter."

"BIRTH OF SOPHIA AND THE FORCES OF DARKNESS

After the nature of the immortals was completed out of the infinite one, then a likeness called Sophia flowed out of Pistis, with the wish that something should come into being like the light that first existed. Immediately her wish appeared as a heavenly likeness with an incomprehensible greatness. This came between the immortals and those who came into being after them, like what is above. It was a veil separating people from the things above.

Now, the eternal realm of truth has no shadow within it because the immeasurable light is everywhere within it. Outside it, however, is a shadow, and it was called darkness. From it appeared a power over the darkness. And the powers that came into being afterward called the shadow the limitless chaos. From it every kind of deity was brought forth, one after another, along with the whole place. Consequently, the shadow too is subsequent to what was in the beginning. The shadow appeared in the abyss, which is derived from Pistis, whom we have mentioned.

The shadow perceived that there was one stronger than it."
