So, what does penetrating the veil truly entail?

[Unbound]

I do see your point 3D, but at the same time I also have an underlying feeling in me that there is a form of Ra that DOES exist as you have just described. Whether or not this is what was responsible for the Ra contact is another thing. Just as a form of physicality in angels MUST exist by virtue of necessity in the face of infinity. However, once again, whether or not these are in any way involved with our current reality is certainly debatable.
