Unfortunately, that is the reason why this keeps happening. It is not that you are their biggest concern and it is not an indication they will use more severe measures, but that cannot be ruled out either. They are able to do surveillance of people of interest to see what they are doing and then may well intrude in some way to get your attention. If they see you are taking an interest educationally in things that are outside the accepted range of involvement, that is a rather broad and ill-defined array of possibilities. So it is not that they see great danger for them in what you are doing, only that you are seeking outside knowledge, so this is more an automatic tripping of a follow-up routine, not that you have committed a mortal sin and are in danger now, but it does speak to the fact they have their ways to keep an eye on things. They cannot view your divinely protected communications and work, as with the Lightworker Healing Protocol, but they can see other things you might do in talking with others, communicating via email, and so on, so it is something to keep in mind.
