B made a poor teacher, but an excellent subject

Energy transference seems key. Living energy to dead flesh.

Embrace the cycle - Life. Death. Rebirth.

Restoring flesh is simple, but restoring mind?

Mindless dro*** (drones?)I need more

Hints in the ether - energy manipulation

Trapped in a plane

Or by a god

Where is she

Recovering the soul. Impossible, or merely difficult?

Resurrecting flesh seems simple. Logic suggests resurrecting the mind should follow, but problems persist. B's expertise does not extend this far.  Where does one hunt for a soul? What plane? In whose domain? Why won't she come to me?

Enough calling into the void, trying to summon her spirit. This magic is not for those who ask - it is for those who take. Will have her back. And woe the god who stands in my way.

Transference of power - from living flesh to dead - allows reanimating. The greater the power, the greater the reanimation. But restoration? True rebirth? How can it elude me? I will bend this power to my will.

The scrawled out text seems to be the "Enough" paragraph as above.

Now the creator of the video thought there might be a code related to the boxed letters, but in transcribing myself I find that they seem to just be capitals. Some places that should be capitals are not boxed, but that also seems to be in places where the text gets emotional.
