They are not lying, they are just not very clear about what they mean when they use the term ISBE.
An ISBE is a being that IS for the purpose of BEing. It can't be killed. So it can't be made of matter and frequencies inside a physical reality. It's coming from the source, and nobody can kill the source.
People who confuse their bodies with who they are will think after dying that they are the soul now. But when the soul is tampered with, like the zapping within the death traps, they are cut off again. The solution is to let go of the body, even the energy body you have after death, in knowing that it's not you, and that you, as an ISBE which is singularity, will survive even without any physical frequency representation. The zapping then won't affect you.
