The process of examining the eyes, and challenging them to step through a net of light is, in fact, a valid and accurate assessment for the nature of spirits you might encounter. And this was the context in which you were employing those strategies to see if spirits were what they seemed, or were dark. To apply this to an interloper can work as well, and the reason is that when you have a genuine desire to understand the truth of things, on the part of someone you encounter, this carries great weight with the divine realm and will outweigh any short-term inconvenience to them. So if you’re clever in how you go about this, and you leave yourself some leeway and some running room, so to speak, you can do this safely and gain information that will be of value in sorting this issue out for yourself. We have not advertised this because people have not asked directly, nor is it a process many can use, because they lack the requisite skills to create the energy in a neutral way to create the experiment. It is a process you could use to good advantage in those instances when you may be connecting to a being on request of the divine to make the connection, but you can always verify the status of the interview subject with regard to their being in alignment with the light, or not, as the case may be.
