Let's go on...
1. After physical death, the ISBE is "sucked in" into the light and then "zapped".
Conclusion:
If the ISBE manages to not get sucked in, it may be able to circumvent to zapping mechanism. If that was not true, the light wouldn't be necessary at all.
2. The light works like a "fly trap", because it makes you feel good, while in reality it's not good.
Conclusion:
The light has no power over you if you don't believe it. You are free to choose to not go into the light, because if that was not the case, it wouldn't need to manipulate you.
3. Lao Tzu, who apparently was aware of the death traps, wasn't able to not get sucked in.
Speculation:
Evading the light seems to be difficult. Lao Tzu tried to circumvent the light by not wanting to go the wrong way, which essentially is the foundation of his philosophy. But not wanting to do something is wanting to do the opposite. Maybe he was sucked in because the light created an illusion of the Dao, the "right way".
Conclusion:
Evading the light may be possible if you don't want to go anywhere.
Speculation:
Not wanting to go anywhere after physical death forces the prison system to get you violently, thus binding resources. If enough ISBEs stay where they are after physical death, not wanting to go anywhere, the result could be some sort of congestion, eventually overloading the system.
4. The "zapping" occurs after going into the light.
Conclusion:
The zapping cannot occur everywhere. The ISBE needs to be redirected towards the zapping mechanism.
5. The result of the zapping is not remembering anything for a short period of time.
Conclusion:
The ISBE will not lose memories if not zapped.
6. The ISBE is put into a new body while it's in the confused state.
Conclusion:
It's the new body that prevents remembering in the long run, thus preserving the confused state of the ISBE.
7. If the ISBE is put into a functioning body, the memories remain (as in the case of Lao Tzu).
Speculation:
The bad ETs are very invested in manipulating DNA. The goal seems to be to create and maintain bodies that cut off the ISBE from its memories.
Conclusion:
The bodies seem to "repair" themselves on their own, as nature tends to heal what has been adulterated. The DNA can be repaired, leading to enabling the body to regain lost memories. If that was not the case, the bad ETs wouldn't be that much invested into manipulating DNA.
Speculation:
The body can be repaired even within one incarnation, as long as you know what you're doing.
Just for perspective, According to the World Death Clock by Medindia, approximately 106.60 people die every minute 1. This translates to roughly 153,424.70 deaths per day and 56 million deaths per year.
