If I read Robert correctly, good entities like angels interfere only rarely, because they do not want to impose on our free will. They respect us, and therefore do not simply come by if you give them "a call".

Negs have no such policy or respect for us, so it is highly likely they will pester anyone "setting up the beacon". It implies a bit of permission to do so, I guess. They might pose as something good to further their goals...

What exactly do you expect to gain by the experience?
